Telemetry solution for wireless temperature measurement on wheels

Based on the Dx telemetry, a turn-key system for solving contact temperature measurements and other parameters on the wheels of road vehicles is available. Robust, easy-to-install transmitter modules make the system ideal for rough applications on the test track. All measurement signals, such as the temperatures at the brake disc, are digitized directly on the wheels and transmitted telemetrically via mirror antennas to the receiver unit in the vehicle. The receiver synchronously acquires the data of up to 4 transmitters and outputs them as analog signals or a CAN data stream.


  • Precise temperature measurement due to differential sensor inputs with integrated thermal reference point
  • Robust transmitter modules with integrated power supply, waterproof (IP 67) for use in all weather conditions
  • Convenient system check by remote-controlled detection of encoder breakage and additional channels for monitoring system status (battery voltage, temperature in the housing, radio signal reception strength) facilitate monitoring and troubleshooting.
  • Highest interference immunity of the telemetry line due to digital data transmission (resolution 16 bit) with error detection
  • Fast integration into existing measurement technology via the standard CAN and analog interfaces
