Detailed Description

 Technical information

Application:
It is specially designed for power station to measure temperature for 30KW, 60KW power-generating set and concerned equipment. It is used to directly measure temperature of liquid, vapor, gas and solid surface ranging from 200℃ to 800℃ during production process.
Operation Theory:
Thermocouple electrodes are made of two different materials. Temperature difference between measuring end and reference end results in pyroelectric potential , then display meter indicates the corresponding temperature to the pyroelectric potential.
It is based on the change of the resistance value which is caused by the temperature of the material. When resistance value changes , the working instrument will display relevant temperature value.
Main Technical Parameters:
Executive Standard
IEC584
IEC751
GB/T16839-1997
JB/T8622-1997
JB/T8623-1997
Insulation Resistance at Normal Temperature
The insulation between electrode and protection tube of thermocouple shall be no less than 1000 under condition that environment temperature is 20 ± 15℃ ,relative humidity is no more than 80% , and testing voltage is D.C. 500±50V.
The insulation resistance between electrode and protection tube of thermal resistance shall be no less than 100 under condition that environment temperature is 15~35℃ ,relative humidity is no more than 80% .and testing voltage is D.C. 10~100V.
