What kinds of commonly used types of industrial thermometer? In order to meet the needs of practical production, the thermometer is an indispensable testing instrument in the industry, the instrument to tell everyone industry commonly used types of thermometer. A, bimetallic thermometer bimetallic thermometer can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature. Bimetallic thermometer is a round shape into threaded heat bimetallic strip as thermal devices, and put it in a protective sleeve tube, one end is fixed, known as the fixed end, the other end of the connection on a thin shaft, called the free end. Spool at the free end is equipped with a pointer. When the temperature changes, the resulting thermal devices the free end of the rotation, drive the thin axis from the Angle of the pointer changes, corresponding temperature indicator on the dial. Second, the pressure type thermometer thermometer is suitable for measuring all kinds of industrial occasions for copper corrosion medium temperature, if the medium corrosion effects 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. Pressure type thermometer is based on the sealing temperature measuring system and saturated vapor pressure of liquid evaporation temperature, the change of the relationship between the thermometer for temperature measurement. When bulb feel 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. Pressure type thermometer with a bulb small volume, fast response, high sensitivity and direct reading, etc. Three, a body surface temperature and pressure surface temperature and pressure and water meter high, is specially designed for hot water heating system, hot water boiler, swimming pool and other equipment design, be able to give a fast and accurate temperature indicator. High water meter can measure pressure PSI and KPA, and water temperature degrees Celsius and Fahrenheit. Four, solar electronic thermometer solar electronic thermometer is the use of day Yang can provide accurate temperature and wired sensors. It is the light level is higher than 100 lux show, when the light levels drop, using the backup battery to provide power to continue to display circuit. It has a bright, easy to read LCD display.
