The tiny resistance changes can be monitored by a suitable system such as the Instrumentation Amplifier.
The output lead from the Strain Gauge bridge interfaces directly with this unit.
The Strain Gauge Sensor is bonded to a steel strip with the terminations brought out to a resistive bridge network mounted on the main support.
A replacement blade/strain gauge is available separately.
Dimensions 280 x 160 x 65mm overall Monitor the resistance changes when the blade is under strain. Works with Instrumental Amplifier.
