A Strain Gauge Based Torque Transducer (Sensor) for Measuring Dynamical Load In-Rotation

摘要

Torque measurement is paramount in engine and transmission testing, turbine testing, pump testing and testing of gear trains and power measurement within propulsion systems. Monitoring torque can be critical to the performance of axles, drive trains, gear drives, and electric and hydraulic motors. Other in-plant applications include gas and steam turbines. Really, torque is an important factor in anything that rotates or spins on a shaft, spindle or axle. In this research, the shaft will be adapted for the application of a "V shaped" strain gauge; to measure the torque on a rotating shaft. The implementation of the transducer will be executed. This paper also discusses calibration of the transducer with Spider8 measurement electronics, the block diagram of the measuring chain, main points of the measuring software and the measurement accuracy. The transducer is then tested with simulated loads. The structure of a grinder makes it possible for measuring torque with strain gauges on it. This saves wear on the drive system and increases product quality.
