Michigan Scientific’s Wheel Torque Transducer Instrumentation Assembly is ideal for collecting data in wheel applications. The assembly consists of a wheel torque transducer that provides one channel of torque data, a 10 circuit weatherproof slip ring with pulse encoder, and can accommodate multiple strain gage and thermocouple spinning amplifiers all enclosed in a weatherproof housing. The torque transducer attaches 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 that duplicate the critical dimensions of the original rim. The hub adapter fastens to the interior bolt circle of the torque transducer and the rim adapter fastens to the exterior bolt circle. The instrumentation is mounted using MSC wheel mounting components.
Superior data accuracy is achieved by locating precision amplifiers on the rotating side of the slip ring. This configuration greatly improves signal quality because the amplifier is located closer to the sensor, reducing errors due to long lead wires, connector resistance variations, electro-magnetic interference, and temperature gradients across slip ring contacts.
The slip ring/encoder/amplifier assembly includes an adapter plate designed to adapt to a variety of wheel bolt circle patterns. Wire connections are sealed on the stationary end of the slip ring with a weatherproof metal cap with a military style connector. All components in the assembly are durable and designed to withstand severe testing environments.
The Wheel Torque Transducer Instrumentation Assembly can be customized to meet the user’s testing requirements. If additional strain gage and/or thermocouple channels are required, higher channel capacity slip ring models are available. The additional amplifiers may be arrayed around the wheel adapter plate.
