The introduction of pressure type thermometer

Principle, the principle of pressure type thermometer is based on the sealing temperature measuring system of liquid evaporation changes in the relationship between saturated vapor pressure and temperature, and temperature measurement. Bag when I feel the temperature change when temperature, saturated vapor produced the corresponding pressure in the closed system, cause the change of curvature elastic element, make its produce a shift in the free end, again by the displacement amplification mechanism of gear into the indicated value, the thermometer with a bulb small volume, fast response, high sensitivity and direct reading characteristics, almost set the glass rod thermometer, bimetallic thermometer, all the advantages of the gas pressure thermometer, it can be made into shock, anti-corrosion type, and can realize remote contact signals, heat resistance, 0 10 ma, or 4 20 ma signal. Is currently the most widely use scope, performance is one of the most comprehensive mechanical thermometer table. An overview of the pressure type thermometer and the development of the series thermometer table, overcomes the original single instrument performance, poor reliability and the shortcoming of the large package, and to reduce the temperature measuring element size 1/30 or 1/60, creative will be installed on the sensor resistance temperature measuring element, realize the function of mechanical and electrical integration of temperature measurement. Formed by liquid pressure type thermometer for basic thermometer table of far eastone, shock, corrosion, electric contact, multi-function series, such as temperature signal transmitting temperature instrument. Divided into two series, regular and explosion proof type. Applied pressure type thermometer is suitable for measuring all kinds of industrial occasions for copper corrosion medium temperature, if the medium corrosion were role should choose anti-corrosion type. Pressure type thermometer is widely used in machinery, textile, chemical, pharmaceutical, food industry for the temperature measurement and control in the process of production. Anti-corrosion type pressure type thermometer adopts full stainless steel material, suitable for neutral corrosion of liquid and gas medium temperature measurement.
