Bimetallic thermometer correct selection method

Bimetallic thermometer is a kind of measurement in the field of low temperature test instrument. 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 applied in chemical and petrochemical industry; Power engineering; Field of food. Construction machinery and general factory. The following is a small make up to bring about the bimetallic thermometer correct selection method of relevant information. , for your reference. In strict process control requirements of using select a bimetallic thermometer for use in the product on the accuracy of measurement, the actual temperature and the temperature of synchronization is very important. So choose the bimetallic thermometer need several parameters, the more accurate parameters of measurement effect is better. 1, and the characteristics of the medium is measured to provide the parameter is in contact with the medium for our choice and what kind of material has much to do, to extend the service life of bimetallic thermometer are of great help. 2, used to provide the correct use of temperature is the basis of choosing the appropriate temperature range, the right temperature range is the basis of service life and accuracy of the bimetallic thermometer. 3, sensors, the length of the bimetallic thermometer temperature points at the end of bimetallic thermometer stem + 20 mm, bimetallic thermometer in medium temperature sensor measurement point should be placed in the center of the medium temperature. 4, installation and the installation of the equipment or piping should be considered, with the installation of the installation. 5, bimetallic thermometer pointer plate with the direction of protecting tube connection bimetallic thermometer can be divided into axial, radial and universal type 3 kinds.
