As temperature sensor and testing part, thermocouples are always used together with Temperature Transmitters, Thermostats, Indicating Instruments.

They are always used for temperature testing on Liquid, Vapour, Air and Surface of Solid objects.

Working range: 0-1800℃

Thermocouple is a return circuit composed by two different conducting points.

When the temperature of the two conducting points are different, electric thermal currency will be created.

When existing temperature difference between the working junction and reference junction of thermocouple, Indicating Instrument could indicate temperature difference of the electric potential difference in the thermocouple.

Insulation Resistance between electrode and protective well: >1000Ω.m

(at 20±15℃, relative humidity ≤80%, Voltage 500±50 V(DC))
