Control & Process Engineering Trainers

PLC Process (Product Code: SLE/EE/06) is a two-tank water-circulation rig used to practise programmable logic controller (PLC) sequencing and level control of a small process plant in engineering and technical-institute laboratories. Students wire its float switch, tank level sensors, pulsed flow sensor, solenoid valves and variable-speed pump into control exercises as water moves from a reservoir to an upper tank, down to a lower tank and back. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the PLC Process Rig Used For?

The rig gives students a real, visible plant to automate. A typical exercise starts with the float switch confirming there is water in the reservoir; the program then switches the pump on to fill the upper tank and uses that tank's maximum-level sensor to decide when to stop. Opening a solenoid valve lets the water drain to the lower tank, whose own pair of sensors tells the program when to return it to the reservoir.

Because the pump is switched on or off while its running speed is set by hand, learners can compare fill times at different speeds and use the pulse count from the flow sensor to totalise the volume moved. The rig suits ladder-logic courses, instrumentation practicals and final-year projects, and sits comfortably among other engineering lab equipment in India's polytechnics and engineering colleges.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of the PLC Process rig. The rig is built and assembled at the company's own licensed factory at Saha, Ambala, Haryana, India, so engineering colleges, training institutes, dealers and importers buy from the maker rather than from a trader.

Frequently Asked Questions

What is included in the PLC Process rig?
The PLC Process rig comprises two transparent tanks mounted one above the other, a reservoir with a float switch, a variable-speed pump, individually switched solenoid valves, an in-line pulsed flow sensor and two level sensors on each tank. Ask us to confirm accessories for your order.

Does the PLC Process rig come with a PLC?
A programmable logic controller is not listed among the PLC Process rig's components, so treat the controller as a separate item. Tell us which PLC or I/O system you plan to use when you enquire, and we will confirm what can be supplied with the rig.

How does the flow sensor on the PLC Process rig report flow?
The PLC Process rig's in-line flow sensor gives a pulsed output: the pulse frequency is proportional to flow rate and the number of pulses is proportional to the volume passed, so a PLC counter input can totalise volume or work out flow.

Can the pump speed on the PLC Process rig be changed?
Yes, manually. On the PLC Process rig the pump itself is controlled on or off, while a manual control lets the user set its running speed, so students switch the pump from their program and adjust speed by hand to compare filling behaviour.

Who manufactures the PLC Process rig?
The PLC Process rig is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Quotations, repeat orders and questions about spare parts for the tanks, sensors or valves are handled directly by the manufacturer.

Process Trainer (Product Code: SLE/EE/07) is a two-module teaching system used to build and study temperature, level and pressure control loops in engineering college and polytechnic laboratories. Its experiment module centres on a stirred process vessel linked by a heat exchanger to separate heating and cooling loops, while a control module with a mimic diagram gives students access to every connection. The trainer is produced by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Process Trainer Used For?

The Process Trainer lets students see how a real process plant behaves before they automate it. Running the heating loop warms the vessel through the heat exchanger, the cooling loop removes heat through the cooler and fan, and the stirrer keeps the contents mixed so the temperature sensor reads a representative value. From the control module, learners first operate every actuator by hand and record how temperature, level and pressure respond.

With that open-loop data they can close loops through the sockets or the built-in computer interface and compare manual, on/off and PID-type strategies. The unit fits process-instrumentation, chemical-engineering and control-systems practicals, and is a practical choice of lab equipment for technical institutes that want several measured variables on one system.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, and the company is the original equipment manufacturer (OEM) of this Process Trainer. Both the experiment module and the control module are made at its own licensed factory in Saha, Ambala, Haryana, India. Colleges and distributors therefore deal with the maker itself when they need replacement parts or a matching unit for an extra bench — just ask us. Company background is on the ScienceLab profile page.

Pressure Process Training (Product Code: SLE/EE/08) is a water-based pressure-control trainer used to teach closed-loop regulation with industrial-style instrumentation in engineering and instrumentation laboratories. Students set up an industrial controller with auto-tune that drives a pneumatic control valve through a current-to-pressure converter, while a gauge pressure transmitter feeds back the pressure in an accumulator. Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, builds the system at its own factory in Ambala, India.

Key Details

What Is the Pressure Process Trainer Used For?

Before an experiment, students fill the reservoir with clean water and prime the system. They then set the controller to regulate the flow of water through the pneumatic valve; as the valve opening changes, so does the pressure in the accumulator, which the pressure transmitter reports back to the controller to close the loop.

Because the trainer combines an industrial controller, an I/P converter and a pressure transmitter, it prepares learners for the loop-checking and tuning tasks they will meet on real plant. The two-channel chart recorder lets a class capture two signals together — for example setpoint and measured pressure — so manual tuning can be compared with the controller's auto-tune result. It is well suited to ITIs, polytechnics and colleges building up vocational training lab equipment for instrumentation courses.

OEM Manufacturer

Jain Scientific Equipments Private Limited (trading as ScienceLab) is the OEM for Pressure Process Training. The company assembles the complete trainer — reservoir, pump, valve, accumulator and instruments — at its own licensed factory in Saha, Ambala, Haryana, India. Buyers therefore receive their quotation, and any later request for replacement parts, from the manufacturer itself. More about the company is on the ScienceLab profile.

Frequently Asked Questions

What are the main parts of Pressure Process Training?
Pressure Process Training consists of a reservoir, a three-speed pump, an industrial controller with auto-tune, a pneumatic control valve, a pressure accumulator, a two-channel chart recorder, a current-to-pressure (I/P) converter and a gauge pressure transmitter.

How is pressure controlled in Pressure Process Training?
In Pressure Process Training, the controller regulates water flow through the pneumatic control valve, which alters the pressure in the accumulator. A gauge pressure transmitter measures that pressure and sends feedback to the controller, completing the control loop.

What do students do before running Pressure Process Training?
Before using Pressure Process Training, students fill the reservoir with clean water and prime the system. Once it is primed, they set the controller to regulate the flow of water and watch the accumulator pressure respond on the chart recorder.

Does Pressure Process Training need an air supply for the pneumatic valve?
Pressure Process Training uses a pneumatic control valve driven through an I/P converter, and pneumatic devices of this kind work from an air supply. The air requirement is not listed in the product details, so please confirm it with us before installation.

Thermal Control Process Apparatus (Product Code: SLE/ETC/01) is a temperature-control process plant used to teach how heater power, air flow and flow restriction combine to hold a process temperature in control engineering laboratories. It models a common industrial process such as an air-conditioning plant, with scaled-down time constants so experiments fit into a normal laboratory session. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Thermal Control Process Apparatus Used For?

The block settles at a steady temperature when heat gained from the electric heater balances heat lost by convection and conduction to the moving air. The control problem is to keep that process temperature within acceptable limits while conditions change, using heater power, fan speed and vane rotation singly or in combination.

Students can begin with single-loop heater control, then treat fan speed or vane position as a disturbance, and finally explore multi-input strategies. Comparing the two sensors shows clearly how measurement lag — added on purpose by the insulating spacer — makes a loop harder to tune. For universities and colleges sourcing engineering lab equipment, the apparatus turns slow thermal behaviour into experiments that can be completed within one practical.

OEM Manufacturer

The Thermal Control Process Apparatus is made by Jain Scientific Equipments Private Limited, the company behind the ScienceLab name, which is the OEM for this unit. Production takes place at its own licensed factory in Saha, Ambala, Haryana, India, and orders go out factory-direct to colleges, research groups, dealers and importers.

ScienceLab is a registered MSME (Udyam UDYAM-HR-01-0003714), and export consignments move under Importer-Exporter Code AAECJ8618A issued by the DGFT. See the ScienceLab company profile for more background.

Frequently Asked Questions

What controls the temperature in the Thermal Control Process Apparatus?
Temperature in the Thermal Control Process Apparatus is controlled by regulating the electrical energy to the heater, varying the air flow rate from the variable-speed fan and rotating the servo-driven vane, used singly or in combination.

Why does the Thermal Control Process Apparatus have two temperature sensors?
The Thermal Control Process Apparatus uses two sensors so students can compare measurements. One sits in direct thermal contact with the block; the other is mounted on an insulating spacer, adding thermal inertia and variable time constants to the control loop.

Are experiments on the Thermal Control Process Apparatus slow?
No. Experiments on the Thermal Control Process Apparatus are kept short because the apparatus has scaled-down time constants for shorter laboratory time. Actual durations depend on the exercise and settings the instructor chooses.

What is the servo-driven vane on the Thermal Control Process Apparatus for?
The servo-driven vane on the Thermal Control Process Apparatus is mounted after the fan and the process block. It creates a variable downstream restriction to the air flow, which is used for more advanced control experiments.

Who manufactures the Thermal Control Process Apparatus?
Jain Scientific Equipments Pvt Ltd (ScienceLab) is the OEM manufacturer of the Thermal Control Process Apparatus, producing it at its own licensed factory in Saha, Ambala, Haryana, India. Repeat orders and spare-part questions for the apparatus are handled by the manufacturer directly.

Coupled Tanks Apparatus (Product Code: SLE/ETC/02) is a liquid-level control trainer used to investigate basic and advanced control engineering principles with one or two interconnected tanks in university and college laboratories. A variable-speed pump fills the left-hand tank, a connecting valve brings in the second tank for two-tank work, and each tank has a level sensor plus a scale for checking its calibration. Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, makes it at its own factory in Ambala, India.

Key Details

What Is the Coupled Tanks Apparatus Used For?

The basic control problem is to regulate the liquid level in one of the tanks by varying the speed of the circulating pump. With the connecting valve closed, students work with a single tank — a simple first-order process — and later open the valve to couple the tanks, creating an interacting two-tank system that is noticeably harder to control.

Having both a rotameter and an electronic flow meter lets learners check the pump's delivery by eye while also measuring it electrically, and the tank scales let them confirm the level sensors before relying on them. Beyond PID practicals, the apparatus suits modelling, system identification and advanced approaches such as fuzzy logic, making it a flexible piece of lab equipment for technical institutes and universities.

OEM Manufacturer

Jain Scientific Equipments Private Limited trades as ScienceLab and is the original equipment manufacturer of the Coupled Tanks Apparatus. Each unit is produced at the company's own licensed factory at Saha, Ambala, Haryana, India, rather than bought in from a trader. Quotations for a single bench or a full laboratory set come from the factory itself. The ScienceLab profile has more about the company.

Students who have worked through level control on the Coupled Tanks Apparatus can move on to these related trainers.

• PLC Process — two-tank rig with solenoid valves and a float switch for sequencing practice
• Process Trainer — level, temperature and pressure in one process vessel
• Controller — analogue PID and phase-lead blocks for closing the level loop
• Digital Interface — computer monitoring and control of the tank signals

The complete range is in the Control & Process Engineering Trainers category.

Frequently Asked Questions

How many tanks does the Coupled Tanks Apparatus have?
The Coupled Tanks Apparatus has two tanks. The pump fills the left-hand tank, and a valve connects it to the second tank when needed, so the same unit covers both single-tank and two-tank experiments.

How is flow measured on the Coupled Tanks Apparatus?
The Coupled Tanks Apparatus measures flow in two ways: a rotameter-type flow meter shows the flow rate visually, and an electronic flow meter measures it for signal-based monitoring and control work.

How can students check the level sensors on the Coupled Tanks Apparatus?
Each tank on the Coupled Tanks Apparatus has a scale, so students can compare the visible water level with the level-sensor output, which is proportional to the water level, and confirm the sensor calibration before experiments.

Which control methods can be studied with the Coupled Tanks Apparatus?
The Coupled Tanks Apparatus supports study of static and dynamic systems, fluid transport and liquid-level control, from basic feedback loops to advanced strategies such as fuzzy logic. The core task is regulating tank level by varying pump speed.

Ball and Beam Apparatus (Product Code: SLE/ETC/03) is an unstable-system control trainer used to teach active feedback control of a naturally unstable double integrator in control engineering laboratories. A steel ball rolls on two parallel tensioned wires carried by a centre-pivoted beam, while a servo motor tilts the beam and sensors report beam angle and ball position. The apparatus comes from Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, and is made at its own factory in Ambala, India.

Key Details

What Is the Ball and Beam Apparatus Used For?

The basic control problem is to vary the beam angle so the ball stays at, or moves to, a chosen position. Left alone, the ball simply rolls to one end — which is exactly why the apparatus is valuable: students must design a controller that actively stabilises the system rather than merely speeding up one that is already stable.

A common teaching sequence starts with an inner loop on beam angle through the servo motor, followed by an outer ball-position loop using phase-advance (lead) compensation. The comparison with launch-vehicle stability makes the theory memorable for aerospace, mechatronics and electrical students, and gives engineering lab equipment collections a very visible demonstration of instability.

OEM Manufacturer

ScienceLab is the brand under which Jain Scientific Equipments Private Limited sells its own laboratory equipment, and the company is the OEM for the Ball and Beam Apparatus. The unit is fabricated and assembled at its licensed factory in Saha, Ambala, Haryana, India. Because buyers deal with the manufacturer directly, questions about a replacement ball, wires or other spares can simply be put to us. Learn more on the company profile.

• Controller — phase-lead, proportional, integral and PID blocks for building the stabilising loop
• Digital Interface — computer input/output for running digital controllers

Find all servo, process and control apparatus in the Control & Process Engineering Trainers category.

Frequently Asked Questions

Why is the Ball and Beam Apparatus unstable?
The Ball and Beam Apparatus is a double integrator: tilting the beam makes the ball accelerate, and its position keeps changing unless the angle is corrected. This makes it naturally unstable, so it needs active feedback control using phase-advance methods.

What sensors are fitted to the Ball and Beam Apparatus?
The Ball and Beam Apparatus has sensors that measure the beam angle and the ball position. A servo motor controls the beam angle, giving students both the measurements and the actuator needed to close a position-control loop.

What does the ball roll on in the Ball and Beam Apparatus?
In the Ball and Beam Apparatus, a steel ball rolls freely on two parallel tensioned wires. The wires sit on a beam that pivots at its centre, so changing the beam angle moves the ball along the wires.

What real systems does the Ball and Beam Apparatus represent?
The Ball and Beam Apparatus represents the control problems of unstable systems, for example a rocket or missile during launch, which needs active control to stop it going unstable and toppling over.

Who manufactures the Ball and Beam Apparatus?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the Ball and Beam Apparatus as the OEM at its own licensed factory in Saha, Ambala, Haryana, India. Buying from the maker means a replacement ball or wire can be requested from the same source.

Engine Speed Control Apparatus (Product Code: SLE/ETC/04) is a speed-regulation trainer used to show the problems of controlling rotating machines, especially non-linear control systems, in engineering laboratories. It uses a scale-model engine driven by compressed air for safety, a motorised valve that sets engine speed, and a d.c. generator that loads the engine output. Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, produces it at its own factory in Ambala, India.

Key Details

What Is the Engine Speed Control Apparatus Used For?

The basic purpose is to adjust the motorised valve so the engine holds a set speed while the d.c. generator loads it. Valves and air-driven engines seldom respond in a straight line, so students meet non-linear behaviour directly and learn why a controller tuned at one operating point may struggle at another.

Advanced sessions use dither signals to compensate for non-linearity, compare single-loop control with multiple-loop and minor-loop structures, build a model from step-response data and design P+I controllers with root-locus methods. Running the model engine on compressed air rather than fuel keeps the exercise safe for teaching, which makes it a practical addition to engineering lab equipment for mechanical, automotive and control courses.

OEM Manufacturer

Jain Scientific Equipments Private Limited — known to customers as ScienceLab — is the OEM for the Engine Speed Control Apparatus and builds it at its own licensed factory at Saha, Ambala, Haryana, India. Engineering colleges, training centres, dealers and importers order directly from the company that makes it, so quotations, repeat orders and spare-part questions are all handled at source. Visit the ScienceLab profile to learn more.

Coupled Drives Apparatus (Product Code: SLE/ETC/05) is a multi-variable drive trainer used to study the control of speed and tension in belt-coupled drives in control and electrical engineering laboratories. Two electric motors are linked by a continuous flexible belt that also passes over a swinging arm, where a jockey wheel measures belt speed and tension. It is built by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Coupled Drives Apparatus Used For?

In a coupled drive, changing either motor's torque affects belt speed and belt tension at the same time, so the two outputs interact. Students first control speed and tension separately, then attempt simultaneous control of velocity and tension, and discover why a multi-variable system needs a coordinated strategy rather than two independent loops.

Adjusting the spring tension at the swinging arm changes the plant, giving instructors a simple way to test how robust a controller is. The same problems occur in magnetic tape drives, textile machines and paper mills, which helps mechanical and electrical students connect theory to industry — a useful addition to any technical educational equipment list.

OEM Manufacturer

The Coupled Drives Apparatus is an OEM product of Jain Scientific Equipments Private Limited, which trades as ScienceLab. It is manufactured at the company's own licensed factory at Saha, Ambala, Haryana, India and dispatched from there to universities, colleges, dealers and importers.

Ball and Hoop Apparatus (Product Code: SLE/ETC/06) is an electromechanical servo trainer used to demonstrate position and velocity control, and to model liquid-slop dynamics, in control engineering laboratories. A steel ball rolls inside a hoop that is free to rotate under servomotor control, while transducers output both the hoop position and the ball position. The trainer is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Ball and Hoop Apparatus Used For?

At its simplest, students close a servo loop on hoop position or speed and study the response. The richer exercises come from the ball: once the hoop is under angular position control, the ball swings like a cylindrical pendulum, adding an oscillating motion that the controller has to take into account.

That pendulum-like motion is a laboratory model of liquid slopping about in a moving container — the same issue designers face with aircraft and missile fuel storage, fuel tankers and industrial pumping systems. Students can try to move the hoop briskly while keeping the ball's swing small, a practical introduction to oscillation control for mechatronics and control courses that rely on engineering educational equipment.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM that makes the Ball and Hoop Apparatus at its own licensed factory in Saha, Ambala, Haryana, India. Institutions and distributors buy it straight from the factory, and follow-up needs such as spare parts or additional units can be raised with the same team.

The company is registered as an MSME under Udyam number UDYAM-HR-01-0003714 and holds Importer-Exporter Code AAECJ8618A from the DGFT for its export shipments. Read more on the ScienceLab profile.

Frequently Asked Questions

What does the Ball and Hoop Apparatus demonstrate?
The Ball and Hoop Apparatus demonstrates electromechanical servo systems for position and velocity control. Because the ball behaves like a cylindrical pendulum inside the rotating hoop, it also models liquid-slop dynamics for more advanced studies.

What signals does the Ball and Hoop Apparatus provide?
Transducers on the Ball and Hoop Apparatus give outputs of the hoop position and the ball position. Students use them to close the servo loop on the hoop and to observe or control the ball's pendulum-like motion.

What is liquid slop, and why model it with the Ball and Hoop Apparatus?
Liquid slop is the sloshing of liquid in a moving container. The Ball and Hoop Apparatus models it with a ball swinging inside a hoop, which is relevant to aircraft missile fuel storage, fuel tankers and industrial pumping systems.

What drives the hoop of the Ball and Hoop Apparatus?
The hoop of the Ball and Hoop Apparatus is free to rotate but is controlled by a servomotor. Students command the servomotor to set the hoop angle or speed and then watch how the steel ball responds.

Servo Trainer (Product Code: SLE/ETC/07) is a d.c. servo control trainer used to teach position and speed control with typical industrial techniques in electrical and control engineering laboratories. A d.c. servomotor, d.c. generator and flywheel share one shaft, with an electric clutch that engages a 30:1 reduction gearbox for position work and a panel-mounted digital meter that shows speed. Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, makes it at its own factory in Ambala, India.

Specifications

What Is the Servo Trainer Used For?

Students usually begin with speed control, driving the servomotor with an analogue signal and reading speed from the optical sensor, then load the shaft with the d.c. generator to see how well a controller rejects disturbances. Engaging the clutch switches to position control through the reduction gearbox, with the manual control providing the position setpoint.

Swapping the interchangeable inertia discs changes the plant, so learners can observe the effect on response and stability. For advanced work, the included block circuits introduce adjustable deadzone, anti-deadzone, hysteresis and saturation — the non-linearities that make real servos misbehave — so classes can study and compensate for them. This breadth makes it a versatile piece of electronics lab equipment for polytechnics and engineering colleges.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM responsible for the Servo Trainer. The company manufactures it at its own licensed factory in Saha, Ambala, Haryana, India, so buyers receive quotations and technical answers from the source rather than from a reseller. Colleges adding more benches later can order matching units directly — ask us for current details. See the company profile for more.

• Controller — analogue PID, phase-lead and summing blocks for servo loops

See the complete Control & Process Engineering Trainers category.

Frequently Asked Questions

What control signal does the Servo Trainer use?
The Servo Trainer uses analogue control signals of 0 to ±10 V, which vary the servomotor shaft speed in either direction, so students can drive it from an analogue controller or a suitable interface.

How is speed measured on the Servo Trainer?
An optical sensor on the Servo Trainer measures shaft speed and shows it on a panel-mounted digital meter, so students can read the speed directly while they test their control settings.

What is the gearbox ratio on the Servo Trainer?
The Servo Trainer has a 30:1 reduction gearbox. An electric clutch connects or disconnects the shaft from the gearbox, letting users switch between speed-control studies and position-control studies on the same unit.

Can the inertia of the Servo Trainer be changed?
Yes. The Servo Trainer comes with two extra interchangeable inertia discs (flywheels) for adjusting shaft inertia, so students can compare how a controller performs with lighter and heavier rotating loads.

Which non-linear effects can be added on the Servo Trainer?
The Servo Trainer includes block-type circuits that add fully adjustable deadzone (deadband), anti-deadzone, hysteresis and saturation effects, allowing advanced experiments on how non-linearities affect servo position and speed control.

Who manufactures the Servo Trainer?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the Servo Trainer as the OEM at its own licensed factory in Saha, Ambala, Haryana, India. Extra inertia discs or other spares can be requested from the manufacturer; ask us about availability.

Is a calibration certificate available for the Servo Trainer's speed meter?
Calibration-certificate availability for the Servo Trainer's panel-mounted digital speed meter should be discussed with us before ordering. Include the requirement in your enquiry through the contact page so it can be confirmed in writing.

Controller (Product Code: SLE/ETC/08) is a compact analogue control unit used to assemble industrial-style control loops from patchable circuit blocks in control engineering laboratories. Its front panel carries summing junctions, phase lead, proportional and integral blocks, a complete three-term PID block, a function generator, a digital voltmeter and adjustable potentiometers, plus D/A and A/D interface connections. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Controller Unit Used For?

Instead of a sealed box, students see each function of an industrial controller as a separate block and connect the blocks through their sockets to build the structure they want — from simple proportional control to full PID with a phase-lead stage. The function generator provides test signals, and the digital voltmeter lets them read signal and setpoint values directly.

Once built, the loop is connected to a plant from the range and tuned on real hardware. The D/A and A/D connections also let a computer take part, so the same unit supports comparisons between analogue and digital control. It is a natural companion when institutions assemble engineering lab equipment for control practicals.

OEM Manufacturer

The Controller is manufactured by Jain Scientific Equipments Private Limited, which does business as ScienceLab, as the original equipment manufacturer. Assembly takes place at its own licensed factory in Saha, Ambala, Haryana, India, and units are supplied factory-direct to institutions, dealers and importers.

Procurement teams completing vendor forms can use the company's GSTIN, 06AAECJ8618A1ZT, and its Legal Entity Identifier, 3358004HRD1JIVXKYX49. The ScienceLab profile has more company information.

Digital Interface (Product Code: SLE/ETC/09) is a computer interface unit used to connect laboratory control apparatus to a PC for signal monitoring and computer-based control in engineering laboratories. It converts analogue signals from equipment into digital form for the computer, and turns the computer's digital outputs back into analogue control signals, handling up to eight inputs and four outputs. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Digital Interface Used For?

Many control courses now implement controllers in software. The Digital Interface makes that possible on physical hardware: sensor signals from an apparatus are digitised for the computer, the control algorithm runs on the PC, and the resulting outputs are converted back into analogue signals that drive pumps, heaters or motors.

With eight inputs, several measurements — for example two tank levels plus a flow reading — can be monitored at once, while four outputs cover experiments with more than one actuator. Choosing the Digital Interface instead of the Controller suits labs that already have their own analogue controllers, or that want benches centred purely on computer control, and it slots easily into existing engineering lab equipment in India and abroad.

OEM Manufacturer

Jain Scientific Equipments Private Limited, the company behind the ScienceLab brand, is the OEM of the Digital Interface and produces it at its own licensed factory in Saha, Ambala, Haryana, India. Because the maker supplies it directly, institutions can ask the same team about matching it to existing apparatus, adding units for more benches or obtaining replacement parts. The ScienceLab profile explains more about the company.
