Specification WSS temperature thermometer bimetal oil temperature gauge
The advantages of bimetal thermometers are fast response, small size, good linearity and stability, and some foreign products also have high temperature performance.
The thermoelectric potential of the bimetal thermometer is only related to the thermoelectric properties of the hot electrode material and the temperature difference between the two ends.
Using the same homogeneous conductor or semiconductor to form a circuit will not generate thermoelectric potential.
The temperature of the two junctions of the thermocouple is T, T0. If T=T0, the thermoelectric potential of the thermocouple is zero. The law of intermediate temperatures provided the basis for the development of thermocouple scales.
If the two conductors A and B are respectively formed with the third conductor, the thermoelectricity has a wide temperature measurement range, and the physical and chemical properties of long-term use are stable.
High conductivity, small temperature coefficient of resistance; ※The thermoelectric potential of the configuration is highly sensitive, and the thermoelectric potential and temperature are linear, easy to copy, simple in process and cheap in price.
But the compensation bridge matched with nickel-chromium-nickel-silicon was wrongly used, and the balance point of the compensation bridge was 0º C. When the temperature of the cold end is 30º C, and the thermometer indicates a temperature of 900º C, what is the actual temperature of the heating furnace? Use the standard electrode law to determine the components that change with temperature.
Generally, bimetal thermometers are used at low temperatures, and thermocouples are used at high temperatures. If the temperature exceeds 500 degrees, the resistance of the bimetal thermometer will be very large, which may affect the measurement results, and even the measurement results cannot be obtained.
