What is the use of the bimetallic thermometer field?

Bimetallic thermometer is a kind of measurement in the field of low temperature measuring instrument, its working principle is one with two or more pieces of metal laminate composed of multilayer metal together, using two different metal working in the principle of expansion degree of different temperature changes. 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. Our common bimetallic thermometer is used in industrial equipment, so we also call it industrial bimetallic thermometer. But it's not, in recent years, due to technological advances, bimetallic thermometer is very practical field is constantly increasing, today we will explain the use of the bimetallic thermometer area have? Bimetallic thermometer is already widely used in petroleum chemical industry, machinery, ships, power plants, the textile field, hvac equipment, ventilation equipment, and household and other fields.
