Wheel torque transducer, 4,068 N·m

The TW10.8 is a wheel torque transducer for passenger cars that gives one channel of torque data. A four-arm strain gage bridge of 525 Ω measures up to 4,068 N·m (3,000 lbf·ft), which is also its combined steer/camber moment rating. The stainless steel ring, Ø 291.57 × 25.64 mm, is weatherproof sealed and adapts to 12 to 15 in wheels. The output is 1.5 mV/V nominal at up to 10 V excitation, with non-linearity of 0.1 % and hysteresis of 0.05 % of full scale. It is temperature compensated from 24 to 121 °C and usable from −40 to 149 °C, or 177 °C short term.

The hub adapter fastens to the inner circle of twelve holes and the rim adapter to the outer circle of twelve; both are made from a profile of the original rim and duplicate its critical dimensions. The weatherproof slip ring, encoder and amplifier assembly offered for all wheel torque transducers mounts on lug-nut extensions with minimal radial run-out; a restraint rod to a magnetic bracket on the fender holds its stator. With no torque on the wheels, the zero offset is noted, then positive and negative shunts relate the output to the calibrated torque.

The TW10.8 is designed for passenger cars. Michigan Scientific wheel torque transducers gather data used in braking system, vehicle stability and driveline development, to find where energy is lost.
