Series of Explosion-Proof Sheathed Thermocouple and Thermal Resistance with
Temperature Transmitter and Display

1.General
Explosion-proof sheathed thermocouple or thermal resistance with temperature transmitter and display is a new-style temperature measurement instrument,a subassembly of which single 2-wired temperature transmitter is completely digital output with 4-20mA by LCD on the spot,with respect to sensor element take the form of spring-loaded,thereby making it gather the features of both the thermocouple (thermal resistance) and bimetallic thermometer.It is application in petroleum industry and chemical industry,light industry and power industry,also used in the places of explosive mixtaues existing with high hydrocarbon content in mediums of air or steam or light fog and so on,as for temperature measurement range from-200 to 1000℃,it is especially suitable for measurement in high temperature of mediums while the bimetallic thermometer is not available.
