Intelligent And Explosion Proof Temperature Transmitter

Model: WR-207


WR-207 Intelligent And Explosion Proof Temperature Transmitter adopts PT100, N, K, J and other temperature sensing components, he resistance signal is converted into the standard 4-20mA current signal through the circuit processing module, which can be used as an integrated temperature transmitter to directly output the 4-20mA signal in the industrial field. In this way, the expensive compensation wire is omitted, and the anti-interference ability of the signal in the long-distance transmission process is improved.


  • High shock resistance, moisture resistance and suitable for harsh field environment installation;
  • High precision, low power consumption, wide ambient temperature range, stable and reliable operation;
  • Fast thermal response time and long service life;
  • High mechanical strength and good pressure resistance;


In chemical plant, there are various flammable and explosive chemical gases around the production site. It’s unsafe and easy to cause environmental gas explosion if use common thermocouples, it needs to use flameproof thermocouple as temperature measurement instrument in these cases.
