Eurosens DPS A(485, CAN)

Eurosens DPS sensor converts air pressure in the air suspension line to the output voltage or digital messages via serial RS485 or automotive CAN bus J1939 protocol. A thin-film bridge is used as the pressure transducer.

Eurosens DPS A is a basic model of Eurosens axle load sensor with 0-5 V analog output.

Eurosens DPS RS and DPS CAN have smart CPU and extra features:

  • Networking support. You can connect several sensors to a single GPS tracker using RS485 or CAN bus interface;
  • Built-in calibration tables and axle load calibration onboard in kilos;
  • Up to 3 calibration tables per 1 sensor;
  • Software filtering and smart data processing.

Eurosens DPS 485 uses LLS/MODBUS protocol. Eurosens DPS CAN uses CAN bus J1939 protocol with configurable PGN. After Eurosens DPS installation and wiring are done, calibration should be performed in which you are mapping the output signal to the load on the vehicle suspension.
