WTT - Compact Wheel Torque Transducer - Description

CAEMAX presents a highly compact wheel torque transducer to measure torque in axial direction at the wheels of road vehicles. The new WTT is not only waterproof (IP 67), but due to its integrated radio telemetry also highly compact. Up to four WTT measurement wheels can be operated synchronously from one receiver unit, creating one synchronous data stream. All of this without wiring or elaborate constructions—and highly fail-safe due to digital data transmission!

Fully differential amplifiers (incl. bridge supply) ensure a maximum of noise suppression.

Due to mechanically induced nonlinearities, accurate calibration for each wheel on a special designed test rig is essential. The in-house CAEMAX calibration test rig has been redesigned to offer optimal calibration.

Besides convenient channel parametrization, CAEMAX‘s data acquisition software RemusLAB offers online display of measurement data in physical units. Measurement data from the WFT can be stored in one file with further measurement data from other sources synchronously!
