（1）working principle
The thermal resistance and thermocouple are used as temperature sensing elements. When it senses the temperature change, it obtains a sensing signal through the internal measurement loop, and then through the corresponding conversion amplification and compensation correction processing, the corrected voltage signal is used to control the constant current circuit, and finally outputs a 4~20mA.DC DC signal that is linear with the measured temperature.（2）technical parameter

1、Explosion proof sign EXia Ⅱ CT1 ～ CT6

2、insulation resistance：The insulation resistance between the external terminal and the shell of the instrument shall not be less than 50M Ω.

3、Error limit：

accuracy	Thermal resistance type	Thermocouple type
A	±(0.1%F.S+Thermal resistance error)	/
B	±(0.2%F.S+Thermal resistance error)	±(0.2%F.S+Thermocouple error)
C	±(0.5%F.S+Thermal resistance error)	±(0.5%F.S+Thermocouple error)

4、supply voltage：24V.DC±10%
5、Load resistance：1100Ωmax（Under 360V power supply）

（3）基本接线方式

（4）model

Intrinsically safe thermal resistance or thermocouple temperature transmitter □-WZPKJ_□-□40i □-WR□KJ_□-□4□i

Integrated thermal resistance and thermocouple temperature transmitter □-WZPKJ_□-□30 □-WR□KJ_□-□3□

To enhance the function, any thermal resistance or thermocouple can be equipped with a temperature transmitter.

Our thermal resistance or thermocouple can be matched with any domestic or imported temperature transmitter (HONEYWELL ROSEMOUUNT MOORE, Germany GMC, UK STATUS, etc.)
