Product brief introduction: usually and instrument display, recording instruments, such as supporting the use of electronic computer, the output 4-20mA, direct measurement of the production site in presence of carbon chlorine compounds explosives -200℃ -1300 ℃range for liquid, gas and steam quality of solid surface temperature.

2, features

Two wire output 4-20mA, strong anti interference capability;

Save wire compensation and installation costs of temperature transmitter;

Safe and reliable, long service life;

Cold end temperature automatic compensation, nonlinear correction circuit;

3, work principle

Explosion proof thermocouple using gap explosion-proof principle, when the cavity when the explosion occurred, can pass through the gap of joint surface flameout and cooling, so that after the explosion flame full temperature delivered to the outside of the cavity, thereby explosion-proof.

Thermocouple ( thermal resistance) produced by thermoelectric power ( resistance ) through the temperature transducer bridge unbalance signal, amplified and converted into4-20mA DC signal to the instrument, the instrument will show the temperature value corresponding to.
