The wheel torque tranducer TW-2T-12.5K provides a real time measurement of the actual torque at the wheel (My), allowing to measure both transmission and brake torque. Both the torque and combined steer/camber moment load ratings of the TW-2T-12.5K transducer are 17000Nm, which fits most of the SUV and light duty vehicles. Highly accurate (non-linearity ≤ 0.1% of FSO, hysteresis < 0,05% of FSO), it has a very low sensitivity to the temperature, thanks to the temperature compensated calibration between 24 and 121°C. Useful on long drive tests, especially when repeated hard brakes increases the temperature, without generating any deviation in the measured data.


TW-2T-12.5K is designed to attach itself to adapters that simulate production wheel rims. The adapter system is fabricated by generating a profile of the original wheel rim and designing a hub adapter and rim adapter, which fasten to the interior and exterior bolt circle respectively and duplicate the critical dimensions of the original rim. The versatility of this system allows the torque transducer to be used with various wheel rim designs, as long as the rim size is >= 16", and the maximum wheel torque does not exceed 17 kNm. High grade stainless steel material and weatherproof sealing combine to provide excellent resistance to corrosion and environmental conditions (rain, snow, ice, mud). The measure is stable over a wide operating temperature range (-40°C à +177°C). In addition, all wires are precisely located to reduce sensitivity to magnetic effects.

Signal acquisition

TTW-2T-12.5K strain gage bridge powering and the output signal transmission to the data acquisition system can be achieved by wire (slip ring) or wireless (telemetry). The transducer outputs a non-amplified signal (1,5mV/V), an amplifier can be added to the slip ring or telemetry in option. The slip ring version can include wheel speed information, as well as addition measurements (temperature, etc...).
