Product Name: Integrated Temperature Transmitter
1, the application
Usually, and display instruments, recording instruments, computer and other ancillary uses, output 4-20mA, direct measurement of the production site exists within the scope of explosives and other carbon- chlorine compounds -200 ℃ -1300 ℃ of liquid, gas and solid surface temperature physical vapor.
Two-wire output 4-20mA, anti-jamming;
Saving temperature transmitter compensation wire and installation costs;
Safe, reliable, long life;
Automatic cold junction temperature compensation, nonlinear correction circuit ;
3, the working principle
The use of space explosion -proof thermocouple principle, when the cavity explosion, through the gap between the flame and cooling joints, after the explosion of the flame temperature does not reach the whole outer chamber, thereby performing explosion .
Thermocouple ( RTD ) generated by thermoelectric power (resistance ) after the bridge temperature transmitter unbalanced signal after amplification converted into 4-20mA DC signal to the working instrument, the working instrument will show the corresponding temperature value .
