Wheel torque transducer for trucks, 9,492 N·m
Of the three rings TW10.8, TW12.8 and TW15.0, the TW15.0 is the largest and has the highest rating: 9,492 N·m (7,000 lbf·ft), which is also its combined steer/camber moment rating. The stainless steel ring is Ø 396.04 mm (15.592 in) by 25.64 mm thick, with a Ø 253.87 mm center bore, and adapts to 15 in and larger wheels. A four-arm strain gage bridge of 525 Ω gives one channel of torque data, with an output of 1.5 mV/V nominal at up to 10 V excitation. Non-linearity is 0.1 % and hysteresis 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 inner bolt circle, Ø 270.03 mm, has eighteen Ø 9.91 mm holes for the hub adapter; the outer circle, Ø 381.46 mm, has twelve for the rim adapter. The adapters are made from a profile of the original rim, and duplicate its critical dimensions. The weatherproof slip ring, encoder and amplifier assembly is an ordering option, as for all wheel torque transducers.
The TW15.0 is made for light and medium-duty trucks. For lighter vehicles, the TW12.8 covers 14 in and larger wheels up to 8.1 kN·m; above the TW15.0, the TW-2T-12.5K measures up to 16,948 N·m on single or dual wheels of 16 in and larger.
