TW-2T-12.5K: wheel torque transducer for single or dual wheels, 16,948 N·m
The TW-2T-12.5K gives one channel of torque data up to 16,948 N·m (12,500 lbf·ft), which is also its combined steer/camber moment rating. The stainless steel body is weatherproof sealed and adapts to a single or a dual wheel of 16 in and larger. The four-arm strain gage bridge is 180 Ω or 525 Ω; the output is 1.5 mV/V nominal at up to 10 V excitation, and the zero balance is within ± 5.0 % of rated output at zero load. Non-linearity is 0.1 %, hysteresis and repeatability 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 temperature effect on zero is 0.005 % of full scale per °C.
The hub adapter fastens to the inner bolt circle of the transducer and the rim adapter to the outer one; both are made from a profile of the original rim and duplicate its critical dimensions. The output connector is a Bendix PTY02E-8-4P.
It is designed for full-size pickups, vans, SUVs and light and medium trucks. For light and medium-duty trucks on 15 in and larger wheels, the TW15.0 is rated 9,492 N·m; for class 8 trucks, the TW-2T-50K and TW-2T-60K-S measure 67 and 81 kN·m.
