◆ Summary
Pors-TR/TC (B) series integrated thermocouple & RTD are generally used with indicator, recorder, PC to measure temperature of liquid, steam, gas and solid’s 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
