The drive-shaft torque sensor system rides directly on the shaft itself, using a bearing grade plastic. The torque-sensor housing is axially constrained using a groove in the housing that interfaces with an mating feature on the sensor housing.
MagCanica offers two variations of drive-shaft torque sensors. The version shown is the larger of the two variations, featuring extensive magnetic shielding, integrated seals, and cutting-edge electronics and firmware that achieves 0.25% in-vehicle accuracy. Only DC power needs to be provided, and the measured torque-signal is returned over CAN along with additional diagnostic information. Rotation of the sensor housing assembly on the driveshaft is prevented by an anti-rotation feature (not shown) which tends to be installation dependent.
