  • Introduction
  • Specifications
4-wire temperature transmitter converts measured temperature signal into DC 1~5V or  DC 4~20 mA. It can form a detection system or adjust system with record, Indicate or adjust instrument to do auto detecting and controlling in production. The temperature scale which matched for this instrument has the same temperature characteristics with temperature component millivolt (or △ R). If user select linear correcting temperature transmitter, you should remark the linear scale when you order regulating or indicating instrument. The transmitter is back rack-mounted. Temperature transmitters are intrinsically safe explosion-proof type. User do not need additional explosion-proof barrier. The explosion-proof grade is ibIICT6
