  • Introduction
  • Specifications
Industrial explosion-proof thermocouple or intrinsically safe thermocouple is a temperature sensor which is widely used in auto-control system. It can convert temperature parameter of controlled object into electrical signals and passes to the display, recording and regulating instruments through the temperature sensor. It is used to test, control and regulate system. In the chemical plant, it often accompanies by a variety of flammable, explosive and other chemical gases, steam, if you use common thermocouples, it is not safe and easy to cause explosion. So In these situations you must use the explosion-proof or intrinsically safe thermocouple as a temperature sensor. Our explosion-proof or intrinsically safe thermocouple products are applied in dIIBT4 ~ dIICT6, ibIIBT4, iaIIBT4, iaIICT6 temperature range group which has explosive gas.
Our explosion-proof or intrinsically safe thermocouple technical performance is in line with JB/T9238-1999technical requirements of industrial thermocouples and GB16839.1-1997 Thermocouple first part: Indexing Table; GB16839.2-1997 thermocouples Part II: allowable error.
At the same time, products are in line with GB3836.1-2000、GB3836.2-2000 standard. The products’ drawings and technical documentation are approved and issued by the national instrument Supervision and get explosion-proof certification.
