Product Description

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.
