Product Details

1Power station thermocoupleapplication

Specializing in power station design, it can meet the temperature measurement needs of 300000, 600000 kW and other generator sets and auxiliary equipment. Directly measure the temperature of liquid, vapor, gas media, and solid surfaces within the range of -200 ° C to 800 ° C in various production processes.

2. Working principle

The electrodes of a thermocouple are composed of two different conductor materials. When there is a temperature difference between the measuring end and the reference end, a thermoelectric potential is generated, and the working instrument displays the temperature value corresponding to the thermoelectric potential.

Thermistor measures temperature by utilizing the characteristic that the resistance of a substance changes with temperature. When the resistance value changes, the working instrument displays the temperature value corresponding to the resistance value.

5. Room temperature insulation resistance

The thermal resistance is tested at an ambient temperature of 15-35 ° C, relative humidity not exceeding 80, and a test voltage of 10-100V (DC). The insulation resistance between the electrode and the outer sleeve is greater than 100M Ω.

The insulation resistance between the electrode and the outer sheath of the thermocouple is greater than 1000 Ω. m when the ambient temperature is 20 ± 15 ° C, the relative humidity is not greater than 80, and the test voltage is 500 ± 50V (DC).
