Bourdon Gauge
Bourdon Gauge (Product Code: SLE/PHY/24) is a dial pressure gauge used to measure and demonstrate positive gas and liquid pressures in general and laboratory work, including school and college physics classes. A substantial black needle reads against a 100 mm diameter white face scaled in kg/cm² and psi, and a clear Perspex back lets students watch the Bourdon mechanism move. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a physics instruments supplier in India for schools, colleges and dealers.

What Is the Bourdon Gauge Used For?
Inside the gauge is a Bourdon tube, a curved, flattened metal tube that tends to straighten as the pressure inside it rises; a linkage turns that small movement into the sweep of the needle. With the Perspex back, students can see this happen while a teacher pumps air into the gauge through rubber tubing pushed onto the rifled inlet. It is used for gas-law work such as pressure against volume, for checking the pressure in a sealed container, and as a readable demonstration dial at the front of the class.
The dual scale lets students compare engineering units, and multiplying the kg/cm² reading by 105 converts it to pascals with enough accuracy for class calculations. Use rubber tubing of 8 mm internal diameter so the connection seals well. The gauge is for positive pressures only: never connect it to a vacuum pump or any other source of negative pressure, as that could damage the apparatus.

Frequently Asked Questions
What is the Bourdon Gauge used for?
The Bourdon Gauge measures positive pressures, those above atmospheric, in general and laboratory use. In physics classes it demonstrates gas pressure and gas-law experiments, and its clear Perspex back lets students see how the Bourdon mechanism moves the needle.
What units does the Bourdon Gauge read?
The Bourdon Gauge has a 100 mm diameter white face with scales in kg/cm² (black) and psi (red). To express a reading in pascals, multiply the kg/cm² value by 105, which is accurate enough for school and college calculations.
What tubing fits the Bourdon Gauge inlet?
The Bourdon Gauge has a rifled metal input tube designed to fit rubber tubing of 8 mm internal diameter. Push the tubing well onto the rifled inlet so the joint holds under pressure, and check it for leaks before taking readings.
Can the Bourdon Gauge be used with a vacuum pump?
No. The Bourdon Gauge is for positive pressures only, that is, pressures in excess of atmospheric. Connecting it to a vacuum pump or any other source of negative pressure could damage the apparatus, so use a gauge meant for vacuum work instead.
Who supplies the Bourdon Gauge?
The Bourdon Gauge is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company handles quotations and dispatch for schools, colleges, dealers and importers in India and international markets.
Is a calibration certificate available for the Bourdon Gauge?
Whether a calibration document can accompany the Bourdon Gauge, code SLE/PHY/24, should be discussed with ScienceLab before ordering. Mention the requirement, quantity and delivery location in your enquiry through the contact page.
