TW9.5: wheel torque transducer for light vehicles, 5.4 kN·m
The TW9.5 is a wheel torque transducer for lightweight vehicles that gives one channel of torque data. Its four-arm strain gage bridge measures up to 5.4 kN·m (4,000 lbf·ft), with a maximum static weight of 455 kg. The ring, Ø 254 mm (10.000 in), is weatherproof sealed to IP67 and adapts to 10 in and larger wheels, which is the smallest rim size of this series. Its wires are placed to reduce sensitivity to magnetic effects. Non-linearity is 0.1 % of full scale or less and hysteresis 0.05 %, at up to 10 V excitation, DC or AC rms. It operates from −40 to 125 °C.
The hub adapter fastens to the interior bolt circle, thirty-two Ø 6.53 mm holes on Ø 187.3 mm, and the rim adapter to the outer circle, twenty-eight Ø 6.53 mm holes on Ø 241.3 mm. Both adapters duplicate the critical dimensions of the original rim and place the tire on the production centerline.
It is used to measure wheel torque on ATVs, utility vehicles, turf-care equipment and other lightweight vehicles. The TW10.8 is designed for passenger cars on 12 to 15 in wheels.
