Product Description

Explosion proof temperature sensor with PT100 thermocouple


WR-201 Series industrial explosion proof temperature transducer, which is used widely in the automatic control system of the chemical industry, it can convert the temperature parameters of control object into electrical signal, and transfer to the indicator, recorder and accommodo meter, to monitor, adjust and control the industrial systems.


In chemical plant, there are various flammable and explosive chemical gases around the production site. Its unsafe and easy to cause environmental gas explosion if use common thermocouples, it needs to use flameproof thermocouple as temperature measurement instrument in these cases.

Explosion proof principle               

It uses the gap flameproof principle and design the sufficient strength junction box and other part. All the components which can cause a spark, arc and dangerous temperature are sealed in the junction box When it happen explosion in the cavity, the joint side can make flameout and cool, to prevent the flame and temperature after explosion from spreading out of the cavity.
