WZPB integrated thermistor

Characteristics of WZPB integrated thermistor:

Two line output 4-20mA, strong anti-interference ability;
Save the cost of compensating wires and installing temperature transmitters;
Safe and reliable, with a long service life;
Cold end temperature automatic compensation, non-linear correction circuit;

working principle
The change in thermoelectric potential (resistance) measured by a thermocouple (resistor) in working state generates an unbalanced signal through the bridge of the temperature transmitter, which is amplified and converted into a 4-20mA electrical signal to the working instrument. The working instrument then displays the corresponding temperature value.
Explosion proof thermocouple (resistor) utilizes the principle of gap explosion-proof. When an explosion occurs inside the chamber, it can extinguish and cool through the gap between the joint surfaces, preventing the flame and temperature after the explosion from being transmitted outside the chamber, thus enabling temperature measurement. The thermoelectric potential (resistance value) generated by the thermocouple (resistor) is amplified by the temperature transmitter's bridge to generate an unbalanced signal, which is then converted into a 4-20mA DC electrical signal and sent to the worker's instrument. The working instrument displays the corresponding temperature value.
