Assembly Thermocouple

I. Application

It is usually connected with display meter, recording meter and computer, etc. to directly measure temperature of liquid, vapor, gas and solid surface ranging from 0℃ to 1300℃ during various production process.

II. Features

1. Easy assembly and convenient for replacement

2. Spring thermal element with good shock-proof performance

3. Wide measuring range

4. High mechanical strength, good pressure-resistant performance

III. Operation Theory

The electrodes of assembly thermocouple are made of different materials. The temperature difference between measuring end and reference end results in pyroelectric potential, then display meter indicates the corresponding temperature to the pyroelectric potential.

IV. Main Technical Parameters

Executive Standard

IEC584

GB/T16839-1997

JB/T5582-1991

V. Insulation Resistance at Normal Temperature

The insulation resistance between electrode and protection tube of assembly thermocouple shall be no less than 1000Ohm. under condition that environment temperature is 20±15℃,relative humidity is no more than 80%, and testing voltage is D.C.500±50V.
