Bimetallic Pressure Gauge And Temperature Pressure Gauge
Temperature pressure gauge can measure temperature and pressure at the same time, by measuring the pressure of the working medium to judge the temperature value, to achieve the dual measurement of temperature and pressure. This instrument has a wide range of application and comprehensive performance, can be manufactured into shock-proof, anti-corrosion type, and can achieve remote contact signal, thermal resistance signal, 0-10mA or 4-20mA signal, is the most widely used performance of the most comprehensive mechanical thermometer.
Working principle The principle of temperature-pressure gauge is mainly based on the change relationship between saturated vapor pressure and temperature of evaporating liquid in a closed temperature measuring system and the principle of expansion of objects under heat. This instrument combines the principle of a pressure thermometer and an expansion thermometer. determines the temperature by measuring the pressure of the working medium.
The temperature is measured by the relationship between the saturated vapor pressure and the temperature of the evaporated liquid in a closed temperature measuring system. When the temperature envelope feels the temperature change, the saturated vapor in the closed system produces the corresponding pressure, causes the change of the curvature of the elastic element, causes the displacement of its free end, then the displacement is changed into an indication value by the gear amplifying mechanism. This kind of thermometer has the advantages of small temperature envelope, fast reaction speed, high sensitivity, direct reading and so on. has almost all the advantages of glass rod thermometer, bimetal thermometer and gas pressure thermometer.
