Smart Temperature Transmitter

Head Mounted Smart Temperature Transmitters

RBT22 Temperature transmitter use PT100/PT1000 temperature sensor as the sensing element, signal is amplified into standard signal such as 4-20mA, RS485 etc. There are linear correction circuit applied in the transmitter, make sure the entire transmitter has very good accuracy.


  • Easy mounting, no need for maintenance.
  • Liquid/gas all available.
  • Multiple output signal optional.
  • Quick response, good accuracy.
  • Excellent long-term stability.
  • Different process connection available.
