Why don't have a bimetallic thermometer with teeth?

Without the teeth of the bimetallic thermometer, installation method, so the applicable installation environment, with simple case insert installation, fixed and can change of cutting sleeve type has the casing pipe ( Insert depth adjustable) Two forms, it is suitable for low pressure piping installation as a temporary test. Temperature measuring element most installations in carbon steel, stainless steel, non-ferrous metals, lining or coating of pipe and equipment, sometimes also installed in the brick masonry, PVC, glass, pottery and porcelain, porcelain pipe and equipment such as sugar. With the casing can quickly change the thermometer when using, more convenient. More convenient for bimetallic thermometer replacement, can replace the bimetallic thermometer under the running condition, do not need to stop the machine to replace, the safety of installation workers can also have very good protection effect. The bimetallic thermometer can be directly measured in the process of various production - 80 - + 500 ℃ within the scope of liquid, steam and gas medium, as well as solid surface temperature measurement. Material for SS304 stainless steel, SS304 have antiseptic effect, especially suitable for chemical pipelines, the price also is very favorable, operation is very easy to use. The principle of the bimetallic thermometer is: with different expansion coefficient of solid combination together two pieces of metal heat element, generally made spiral wound, its one end fixed and the other end with a pointer. When the temperature changes, the thermal component of curvature change, free end rotation, drive the pointer indicates the temperature value on the dial. The bimetallic thermometer is such a kind of simple structure, small body has a greater role in temperature indicating device, it is not only to maintain a simple and cheap, easy to use, safe and reliable, and has great market space to develop and explore.
