How to correctly choose the bimetallic thermometer? Instrument to tell you

Thermometer is varied in life, which use most is the thermometer used in industry, but some people use to choose when they don't know to choose what kind of, how to correctly choose the bimetallic thermometer? Instrument tell you! Bimetallic thermometer is mainly used in industry of element is one with two or more pieces of metal laminate composed of multilayer metal together. In order to improve the temperature measuring sensitivity, will be 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. Bimetallic thermometer and the rod of glass liquid thermometer USES similar, but can be used under the condition of higher mechanical strength. And have waterproof, corrosion resistance, vibration resistance, intuitive, easy reading, no mercury pollution, strong and durable, etc. Alternative to many other line temperature instrument, widely used in petroleum, chemical industry, machinery, ships, electricity, textile, printing and dyeing and other industrial and scientific research departments. In practice, bimetallic thermometer protecting tube of stainless steel material, more pressure, and other significant characteristics of anti-corrosion ability. The structure of the bimetallic thermometer has a variety of styles: type axial and radial type, universal type and other varieties, suitable for all kinds of field according to the needs. We can according to the need of the use of field and using range, choose suitable bimetallic thermometer, please according to the following image decomposition to choose suitable thermometer!
