And characteristics of the bimetallic thermometer industrial application

Bimetallic thermometer mainly element is to use two or more pieces of metal laminate composed of multilayer metal together. Will usually metal bimetallic thermometer is made spiral coil shape. When multi-layer metal temperature change, the layers of metal expansion or contraction, makes the spiral coil rolled up or let go. As a result of the spiral coil end fixed and the other end connected to a free rotating pointer, two kinds of metal is not the same as the amount of volume change as the temperature changes, so will be bent. Its one end fixed and the other end with the temperature change and displacement, displacement and temperature close to the linear relationship. This kind of instrument of temperature measurement range is - 80 ~ 600 ℃, permissible error are two process about 1% of the scale. Can be used under the condition of higher mechanical strength. Bimetallic thermometer is a kind of field detection instrument suitable for the measurement of low temperature, and can be used to directly measure the liquefaction, the temperature of the gas. Bimetallic thermometer compared with domestic similar products: instrument accuracy level is 1. Level 0, instrument shell with anti-corrosion materials, its temperature resistance can be as high as 200 ℃, the lowest for - 40℃。 Dial is printing plate, aluminum surface clear aesthetic appearance. A pointer to aluminium. Bimetallic thermometer is axial, radial and universal type header type selection, etc. Bimetallic thermometer sheath maerial length according to the need to customize. Industrial bimetallic thermometer is widely used in petroleum, chemical, metallurgical, textile, food and other industries. Bimetallic thermometer is a kind of measurement in the field of low temperature test instrument. Can be directly measured in the process of various production - Within the scope of 80 ℃ ~ 600 ℃ liquid steam and gas medium temperature. The scene display temperature, intuitive and convenient safe and reliable, long life; Core-pulling thermometer can not stop short time machine maintenance or replacement. Type axial and radial type, universal type, variety complete, suitable for all kinds of the needs of the installation.
