INQUIRY

Thermocouple with Temperature Transmitter is usually connected with display meter, recording meter, computer, etc. to directly measure temperature of liquid, vapor, gas and solid surface ranging from 0 to 1800°c with output of 4-20mA.
Thermocouple with Temperature Transmitter Features
1.Double wire system output of 4 20mA, good anti-interference performance
2.Spare cost on compensational wire and temperature transmitter installation
3.Wide measuring range
4.Automatic compensation at cold end, non-linear rectifying circuit
Thermocouple with Temperature Transmitter Operation Theory

Pyroelectric potential change tested with the thermocouple (thermal resistance) results in imbalance signal through electrical bridge of temperature transmitter. The signal transforms into D.C. 4~20mA signal after being amplified and is transmitted to working meter, then working meter shows relevant temperature value.
