General industrial use bimetallic thermometer have what characteristics?

Bimetallic thermometer used in industry belongs to a kind of measuring low temperature field instruments, commonly used in industrial equipment, petrochemical industry, heating system, piping, power plants, Marine, etc. Can be used to directly measure the temperature of the different media, now are very common in industrial production, also has many characteristics in use. 1. Mercury-free harm and good stability with different expansion coefficient of two kinds of bimetal thermometer metal pieces together form a thermal components, 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. 2. 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. Using bimetallic thermometer is important to note that the working limits of the bimetallic thermometer should be for the table card temperature three-quarters of the best. Also need regular maintenance and maintenance, to ensure the accuracy of measurement.
