Power station thermocouples are designed for power stations and can meet the temperature measurement needs of 300,000, 600,000, 1,000,000 kilowatt generating units and auxiliary machines. Directly measure liquid, steam and gas media as well as body surface temperature in the range of -200℃~800℃ during the production process. The electrodes of the 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 will be generated, and the working instrument will display the temperature value corresponding to the thermoelectric potential. Resistance measures temperature by using the characteristic that the resistance of a substance changes when its temperature changes. When the resistance changes, the working instrument displays the temperature value corresponding to the resistance.
When the ambient temperature of the thermocouple is 20±15℃, the relative humidity is not greater than 80%, and the test voltage is 500±50V (DC), the insulation resistance between the electrode and the outer tube is ≥1000MΩ.m.
When the ambient temperature of the thermal resistor is 15~35℃, the relative humidity is not more than 80%, and the test voltage is 10~100V (DC), the insulation resistance between the electrode and the outer tube is ≥100MΩ. The thermocouple produced by Deyang Dongfang Yili is suitable for steam pipelines
. , boilers and other occasions that require temperature, pressure, etc.
