Wheel Torque Transducer

Tractor Wheel Torque Transducer
This strain gauge transducer was designed to measure the torque at the wheel of an agricultural tractor.   It was mounted as a spacer onto the axle flange, making for easy installation.   The low profile of the unit meant minimum disruption to the normal geometry.  The strain gauges were sited in such a way that only torsion was measured, radial and thrust loads being self cancelling at all wheel orientations.   Signal connection was made by battery powered short range telemetry.
