Bimetallic thermometer how repair

Bimetallic thermometer is widely used in petroleum, chemical, metallurgical, textile, food, industry. Bimetallic thermometer can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature. If in use damage, bimetallic thermometer how repair? Because the properties of the bimetallic strip, generally damaged to repair, in order to accurate temperature measurement, suggest to buy a new bimetallic thermometer. 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. Bimetallic thermometer to not easy to be damaged during use, should pay attention to is: 1, when measuring the original insertion depth of more than 1 m, shall be installed vertically, as far as possible or add racks and protect casing. 2, bimetallic thermometer in custody, installation, use and transportation process, should try to avoid collision protection tube, do not make. To protect the tube bending and deformation. When installation, it is forbidden to twist the instrument shell. 3, 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. 4, bimetallic thermometer in custody, use the installation and transportation, should avoid collision protection tube, do not make the protection tube bending variant and the table when the spanner is used.
