Product Details

Brief Description

Armored thermocouple has many advantages, such as flexible, high pressure- resistant, fast thermal response time and durability and so on. it is can be used as a temperature sensor which is the same to the industrial fabricated thermocouple. It is usually used with display instrument, record instrument and electronic regulator, at the same time, also can be temperature components for the fabricated thermocouple. In the process of production it can directly measure all liquid, steam and gas and solids surface temperature from 0℃~800 ℃, should comply with GB/T18404-2001 standard.
