Precise and robust
The WTT-Dx, which is waterproof according to an IP67 protection rating, acquires the torque in the axial direction (My) by means of integrated strain gauge sensors. The fully differential design of the strain gauge amplifier, including the bridge feed, ensures maximum interference suppression.
Thanks to the clever design of the sensor housing, the WTT-Dx also delivers high-precision measurement data even during dynamic maneuvering which causes high temperatures. The mechanical stability of the sensor housing is designed to last for multiple vehicle lifetimes of heavy SUVs.
To enable measurements in snow, ice and condensation, the sensor housing, power supply and electronics were integrated into a water-tight (IP67) housing. The special rechargeable batteries installed in the sensor allow measurements at a temperature range of -30 °C to + 60 °C.
Wireless data transmission
Each WTT wheel torque transducer is equipped with a Dx-telemetry digital transmitter unit. Measurement data from up to four WTTs are transmitted wirelessly from the wheel to receiving antennas on the outside mirrors - thanks to digital technology, interference-free and high-resolution. The Dx-transmitter units integrated in the wheels are centrally controlled and clocked by the receiver unit in the vehicle. This highly simultaneous sampling of all four wheels makes it possible to detect and validate fast control processes between the wheels with high temporal precision. Measurement data are output at the receiver unit via CAN or analog and can therefore be easily integrated into existing measurement systems.
- 轮辋适配器:
和普通轮辋一样，轮辋适配器用于安装轮胎。轮辋适配器不因车型不同而不同，仅仅和轮胎尺寸有关。因此，拥有相同轮胎尺寸的不同车型可共用轮辋适配器。li> - 轮毂适配器:
轮毂适配器用于连接车辆和传感器，对于不同车型，只要车轮螺栓和车轮偏置相同，轮毂适配器可通用。因此，只需几个不同的轮辋适配器便足以覆盖所有车型。 - WTT-Dx传感器壳体:
WTT-Dx传感器壳体:传感器壳体连接于轮辋适配器和轮毂适配器之间。
基于该模块化设计，WTT-Dx在节省经济、时间和空间成本的同时，可快速应用于多种不同车型
Test-ready in just an hour
The installation of a WTT-Dx is almost as easy as a wheel change - four WTTs can be mounted in one hour. Thanks to an uncomplicated system set-up and convenient software functions, such as the zero calibration, the system can be test-ready within a very short time.
