Bimetallic thermometer have what characteristics?

Bimetallic thermometer is a kind of low temperature measuring instrument, which can be used to directly measure the different liquid, steam and gas now are very common in industrial production, also has many characteristics in use. First, no mercury pollution and good stability with different expansion coefficient of two kinds of bimetal thermometer metal solid combination together temperature sensing 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. Second, durable and affordable general materials for SS304 stainless steel bimetal thermometer, SS304 have antiseptic effect, especially suitable for chemical pipelines, the price also is very favorable, operation is very easy to use. Need special told everybody is here for the bimetallic thermometer is normally in low temperature environment, if in the use of more than five baidu high temperature, it will greatly affect the measurement result, at the same time the thermometer itself can also cause some damage.
