TWO wire 4-20mA,Save compensation wire,High anti-interference ability. Linearization function,Automatic compensation for cold. Safe and reliable life. Site parameter setting,facilitate user With Hart or not FDWR series armored thermocouples use homogeneous conductors (A electrode and B electrode) to form a closed loop. When the two contacts are at different temperatures, current flows through the loop, and there is a thermal electromotive force between the two contacts. The electromotive force is related to the average temperature. The material of the conductor is related to the temperature difference between the two ends. Thermocouples use this principle to measure temperature. Usually used in conjunction with display instruments, recording instruments, computers, etc., to directly measure the surface temperature of gases, liquids and solids in the range of 0°C to 1700°C in various production processes.
