Product Description

Explosion-proof and intrinsic safety type thermocouple is a temperature sensor, widely applied in the chemical industrial automatic control system. It transfers the object temperature to electrical signal, and sends it to display, record and adjusting instruments, to test, regulate and control the system.

In chemical plant, the production field is often accompanied with various inflammable, explosive chemical gas & steam, it’s not safe to use common thermocouple which is easy to result in gas explosion. Therefore, explosion-proof and intrinsic safety type thermocouple is necessary. Our explosion-proof and intrinsic safety type thermocouple are used in these dangerous occasions of which temperature group zone are dII BT4 ~ dII CT6, ib II BT4, ia ll BT4, ia ll CT6.
