Power Station Special Thermocouple
1.The application
Professional for power station design, can satisfy 300000, 600000 kw generators and auxiliary engine temperature measurement needs.Direct measurement in the process of various production - 200 ° C to 800 ° C range of liquid, steam and gas medium, as well as solid surface temperature.
2.Work principle
he thermocouple electrode is composed of two different conductor material.When measuring the temperature difference is with the reference, the can produce thermoelectric power, the instrument will show thermoelectric potential corresponding temperature value.
Thermal resistance is the use of the material when the temperature changes, its resistance also along with the change of characteristics to measure temperature.When resistance changes, the work shows the temperature resistance of the meter.
