The T312 Universal Mount Automotive Wheel Torque Sensor is installed between the vehicle’s wheel hub and brake drum with the wheel’s tracking centerline offset 1.5 inch. The universal sensor can be mounted on most vehicles with 4 or 5 wheel bolt patterns. The included adapter set facilitates the attachment of the T312 to the user-specified drum and wheel-bolting pattern. A special wheel can be provided that will return the wheel’s tracking centerline to its original position. A slip ring assembly interconnects the wheel torque sensor and the vehicle’s on-board instruments. Contact SensorData Technologies to discuss a T312 configured to meet your special needs for a wheel torque sensor. Also refer to SensorData’s T212 for a transformer coupled wheel torque sensor similar to the T312.

The T312 sensor can be used for almost any conceivable wheel torque measurement requirement. The adapter set that is supplied with the T312 allows the user to install the T312 on a specified vehicle. Additional adapter sets can be ordered for other applications without having to order a new sensor. The T312 can be configured for use on almost any vehicle with a four or five wheel bolt pattern and with bolt sizes ranging from 0.375 to 0.500 inch or their metric equivalents. The T312 can be supplied with a speed sensor and/or shaft encoder and with a rotary transformer coupled sensor in place of the slip ring coupled sensor (refer to T212 data sheet). If your requirement for the T312 requires a design that varies from that shown above, please consult the factory to discuss a T312 package that is ideally suited to your special needs.
