Summary
    Pors-TR/TC (B) series integrated thermocouple & RTD are generally used with indicator, recorder, PC to measure temperature of liquid, steam, gas and solids surface within range of 0~1800, export 4-20mA.

Features 
   Two wire 4-20mA output, high anti-interference;
   Save cost for compensation wire and installation of temperature transmitter;
   Wide measuring range;
   Cold-junction automatic compensation, non-linear calibration circuit;

Standard: The sensors are made complying with standard:
   IEC60584,  IEC1515, IEC60751, JB/T7391-94
