Configurable System for Temperature Measurement with CAN FD Interface

MU-Thermocouple1 CAN FD (Measuring Range J)


MU-Thermocouple1 CAN FD (Measuring Range K)


MU-Thermocouple1 CAN FD (Measuring Range T)



With the MU-Thermocouple1 CAN FD, measurement data of thermocouples is captured, preprocessed, and transmitted via CAN FD. The temperature is measured via 8 connectors, which are specified for the temperature measuring ranges J, K or T, depending on the product version. Temperatures can be captured in Celsius, Fahrenheit, or Kelvin and processed with an individual scale and offset. The measurement data is then transmitted via CAN FD or classic CAN.

Data processing, message transmission, and LED display are set up with the free Windows software Thermocouple FD Configuration. The configuration created on the computer is transferred via the CAN bus to the MU-Thermocouple1 CAN FD which then runs as an independent CAN node. Multiple devices can be configured independently on a CAN bus.


The configuration requires a PEAK CAN interface.
