Bimetallic thermometer is made up of the parts?

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. Structure bimetallic thermometer is the 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. The bimetallic thermometer is made up of the parts? The instrument will take you to get to know about it. Bimetallic thermometer is made up of a variety of small parts: pointer, pointer shaft, bimetal thermal components, panels, table, pan, cover ring, pan, heat pipe, joints, etc. Bimetallic thermometer is internal structure of the main heat element: a bimetallic strip. Bimetallic strip has a linear spiral and plane spiral, linear spiral bimetallic thermometer is mainly used for probe type, and planar spiral bimetallic thermometer is mainly used for surface and indoor use bimetallic thermometer. When use must pay attention to the following: 1, the bimetallic thermometer is installed on the use of protection tube, in the process of using, it into the medium length, must be greater than the actual length of the temperature sensing element. 2, bimetallic thermometer at the time of use, often immersed in the 100 mm to the length of the control. Measure the temperature in 0 The range of 50 ℃, immersed length must be greater than 150 mm, only in this way can accurately measure the temperature. 3, the bimetallic thermometer safekeeping, either at the time of use, or at the time of transport, must avoid knock against the condition of the existence, more should not have been the use of the bending deformation condition. 4, for bimetallic thermometer is often used, to do regular use of performance check, the best time is inspected once every six months. 5, have the thread gauge is installed wrench must be used when the rotating hexagonal section, it is forbidden to turn the thermometer meter by hand. The bimetallic thermometer operator, in the process of use, must be in strict accordance with the above method to use.
