Pressure thermometer parameters




The principle of a pressure thermometer is based on the relationship between the saturated vapor pressure of the evaporating liquid in the closed temperature measurement system and the temperature, and the temperature is measured. When the temperature sensing changes the temperature, the saturated steam in the closed system generates a corresponding pressure, causing the curvature of the elastic element to change, causing the displacement of the free end, and then the displacement is changed to the indicated value by the gear amplifying mechanism. With small volume, fast response, high sensitivity and intuitive reading, it has almost all the advantages of glass rod thermometer, bimetal thermometer and gas pressure thermometer. It can be made into shockproof and anti-corrosion type, and can realize remote contact. Signal, RTD signal, 0-10mA or 4-20mA signal. It is a mechanical temperature measuring instrument with the widest range and the most comprehensive performance.
