The 20 PT1000 RTD Scanner monitors 20 2-wire PT1000 inputs from a diesel engine and the temperature information is provided to the engine control system over a SAE J1939 CAN bus. Temperature information can include exhaust temperature, winding temperature, and fluid temperature. All channels of temperature data are automatically sent over the CAN bus when power is applied with no additional programming or configuration required. The RTD Scanner is designed to meet the environmental, EMC and vibration requirements of vehicle and power generator set applications.
