热偶真空计广泛应用于压力测量。其原理是根据气体随压力改变其导热性的这一性质。在连接被测对象的压力计灯泡里有一放热丝。根据气体的压力和导热性,放热丝的温度发生变化。压力计灯泡JIT-2和ⅡMT-2里使用铬镍-考铜热电偶测温,热
Thermocouple vacuum gauge is widely used in pressure measurement. The principle is based on the pressure of gas to change its thermal conductivity of this nature. There is a heat release wire in the pressure gauge bulb that connects to the object under test. Depending on the pressure and thermal conductivity of the gas, the temperature of the exothermic wire changes. Pressure gauge bulb JIT-2 and IIMT-2 use chromium nickel - test copper thermocouple temperature, heat
