Motor shaft instrumentation for torque measurement
A machine manufacturer wants to measure the torque that supports one of its motor shafts.
The most cost-effective solution is to instrument the concerned shaft using strain gauges.
To do this, the following operations are required:
- Receipt of drawing of the shaft to be instrumented.
- Manufacturing of two protective half-shells.
- Reception of the shaft to be instrumented.
- Surface preparation in the area where the gauges will be glued.
- Bonding, wiring and closing.
- Theoretical calculation of the output signal based on the diameter of the shaft, its material and the K-factor of the glued gauges.
- Supply of a calibration resistor to facilitate calibration of the indicator.
