Detailed Product Description

The Application of Thermcouple

It is usually used with display-meter, recording -meter and computer etc., outputting 4-20Ma, to directly measure temperature of liquid, vapor, gas medium and solid surface ranging from 0 to 1600^oC during various production processes

The Features

1.Two wire system output of 4~20Ma, strong anti-interference performance

2.Save cost of compensation wire and installation of temperature transmitter

3.Wide measuring range

4.Automatic compensation of temperature at cold end, non-linearity corrceting circuit

The Working Principle

Hydroelectric potential(resistance) of thermocouple(thermal resistance) will bring the unbalanced current signal through the electrical bridge, the signal will be amplified to 4~20 mA D.C. signal and transfer to the instrument, the instrument will display the relevant temperature
