Application
Usually display instruments, recording instruments, computer and other ancillary uses, output 4-20MA. Direct measurement of the production site, such as the presence of carbon-chlorine compounds explosives range -200 ºC -1300 ºC liquid, vapor, gas and solid surface temperature
Works
Explosion-proof thermocouple principle margins of the cavity when the explosion occurred, the gap through the flame and cooling joints, all-temperature flame not pass after bombings outside the chamber, thereby performing explosion
Thermocouple (RTD) generated by thermoelectric power (resistance) after the bridge temperature transmitter unbalanced signal after amplification 4-20MA converted into a DC signal to the working instrument, working instrument will show the corresponding temperature valueFeature
Two-wire output 4-20MA, strong anti-jamming capability
Saving compensation wire and installation cost temperature transmitter
Safe, reliable, long life
Automatic cold junction compensation, non-linear correction circuitThe main technical parameters
