Far eastone identification bimetallic thermometer

Bimetallic thermometer is the use of two different metal working in the principle of expansion degree of different temperature changes. Bimetallic thermometer is mainly used in industry of element is one with two or more pieces of metal laminate composed of multilayer metal together. To improve the temperature measuring sensitivity, is usually made of metal spiral coil shape. When multi-layer metal temperature change, the layers of metal expansion or contraction, makes the spiral coil rolled up or let go. As a result of the spiral coil end fixed and the other end connected to a free rotating pointer, therefore, when the bimetallic strip feel the temperature change, Pointers can be on a circular dividing scale to indicate the temperature. This instrument measuring temperature range is 200 ~ 650 ℃, permissible error are two process about 1% of the scale. The thermometer and the rod of glass liquid thermometer USES similar, but can be used under the condition of higher mechanical strength. Above is the small make up today for everyone to share the identification method of the bimetallic thermometer, my company has always been based on science and technology, the market as the guidance, by its exquisite technology, process and efficient products, perfect after-sales service won the trust of users, thereby obtained the development in the field of product market.
