Application
Assembly type thermocouple which is used in industry as the sensor
measuring temperature is generally connected with displaymeter, recording
meter and electronic regulator to directly measure temperature of liquid, vapor,
gas and solid surface ranging from 0℃ to 1800℃ during various production
process.
Features
Easy assembly and convenient for replacement
Spring thermal element with good shock-proof rformance
Wide measuring range
High mechanical strength, good pressure-resistant
Operation Theory
The electrodes of assembly thermocouple are made of different materials.
The temperature difference between measuring end and rference end results in
pyroelectric potential, then displaymeter indicate the corresponding temperature
to the pyroelectric potential.
Main Technical Parameters
1 Executive Standard
IEC584 IEC1515 GB/T6839-1997 JB/T5582-91
2 Insulation Resistance at Normal Temperature
The insulation resistance between electrode and protection tube of assembly
thermocouple shall be no less than 1000Ω.m under condition that environment
temperature is 20± 15℃, relative humidity is no more than 80%, and testing
voltage is D.C. 500± 50V.
