Bimetallic thermometer installed pay attention to the point

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. Should be paid attention to for the installation of the bimetallic thermometer, temperature measurement accuracy, safety and reliability and convenient maintenance, and shall not affect the equipment operation and production operation, so the bimetallic thermometer installation should pay attention to the following three points: 1, the bimetallic thermometer should fully consider the measuring section when installation and need to have enough heat exchange between medium, so don't be installed in the valve, dead space and elbow. 2, bimetallic thermometer protecting tube immersed in the measured medium length must be greater than the length of the thermal components, generally greater than 100 mm in length, 0 50 ℃ range into greater than 150 mm in length, so as to ensure the accuracy of measurement. 3, bimetallic thermometer in custody, installation, use and transportation process, should try to avoid collision protection tube, don't make the protection tube bending, deformation. When installation, it is forbidden to direct shear instrument shell with the hand, should use wrench throw hexagonal installation.
