Temperature controller thermostat \thermocouple wire 1.All kinds of graduation 2. High stability and accracy

 Temperature controller \thermostat wire

 

Normally, it isassembled with display instruments, recording instruments, computer, etc. It is direct used to measure site temperature of liquid, vapor, gas and solid surface with output 4-20mA.

Feature

Two-wire output 4-20mA, strong anti-jamming capability;

Save the costs of compensation wire and install temperature transmitter;

Safe, reliable, and long life;

Automatic compensation of cold junction temperature, non-linear correction circuit
