Detailed Product Description

The Main Technical Parameters of Thermocouple:

1.Standard:

       IEC 584

       IEC 751

       GB/T 16839-1997

       JB/T   8622-1997

       JB/T   8623-1997

2. Insulation Resistance at Normal Temperature:For thermocouple, environment temperature is 20±15^oC; relative humidity is not over 80%; test voltage is 500±50v(D.V); insulation resistance between electrodes and electrodes, electrodes and outer thermowell is no less than 1000MΩ;

     For thermal resistance, environmental temperature is 15-35^oC; relative humidity is not over 80%; test voltages 10-100v(D.C); Insulation resistance between electrodes and electrodes, electrodes and outer thermowell is no less than 100MΩ.

The Application of Thermocouple:

It is designed specially for power station, which can meet the temperature measurment demand of generator and assistant machine with 300,00 KW and 600,000KW, to measure the surface temperature of the mediums as liquid, steam and gas ranging from -100^oC to 800^oC during various production directly.

The Working Principle of Thermocouple

The two electrodes of sheathed thermocouple are made of different conductor materials. Where there is temperature difference between measuring end and reference end, there will be hydroelectric potential, then the meter shows the corresponding temperature of the hydroelectric potential
