    Description

    Product introduction:

    Model: WREK

    Name: explosion-proof armored thermocouple

    Manufacturer: Shanghai Automation Instrumentation Co., Ltd.

    Application: WREK explosion-proof armored thermocouple is a temperature sensor. It is widely used in automatic control system of Chemical industry. Through temperature sensor,it can transform the temperature parameters of the control object to  electric signals, then delivery them to display instrument ,recorder, regulator, and carry out detection ,control and adjustment to the system. In chemical factories, there are always many flammable and explosive chemical gas, steam, hydrocarbon etc. in production field. It is very dangerous to use normal thermocouple, and will cause explosion of environment gas easily. So, we must use explosive-proof or intrinsic safety type thermocouple as temperature sensor in these places. Besides, it has Multiple explosive-proof types, good explosion-proof performance, compression spring type thermal components, good anti-vibration performance, high mechanical strength and good pressure-resistant properties.
