Jiutian is one of the the China thermocouple suppliers. As a sensor for measuring temperature,industrial assembly thermocouple are usually compatible with display instrument, recording instrument, actuator, PLC and DCS system. It can be used to measure the surface temperature of liquid, steam and gas mediums and solid from 0℃~1800℃ during industrial production.

The temperature measuring for thermocouple is achieved through measuring its thermoelectrical potential.Its two thermodes are temperature sensing elements made of equivalent conductors with two different compositions and one connected ends. In the closed loop made of two kinds of conductors, if different temperature arises on the two endpoints, then a certain thermoelectrical potential will be created.The thermoelectrical potential intensity is not related to the sectional area and length of copper conductor but the properties of conductor materials and the temperature of their two endpoints.
