Thermocouple/duplex thermocouple/flexible thermocouple
Thermocouple/duplex thermocouple/flexible thermocouple
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
