Integrated Thermal Resistance/Thermocouple PT100 Temperature controller
Integrated Thermal Resistance/Thermocouple PT100 Temperature controller
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
