2.20 ELECTRICS SENSOR Specifications The sensor is a sealed unit with a wiring harness and plug attached. The sensor (2) is bonded and secured by three bolts (6) to the top of the rear axle. The type of sensor installed on the machine is known as a strain sensor or strain gauge. The strain sensor measures the change in electrical resistance that results from the amount of strain (stretch) that is applied to the wires in the sensor. Factors that affect the amount of strain applied to the sensor are: 1. The weight of the load that is carried on the work tool. 2. The amount of boom extension. 3. The angle of the boom.
As the electrical resistance in the sensor changes, a change in voltage is measured by the display module. As more strain is applied to the sensor, a greater change in voltage is measured.
