What are the benefits of using bimetallic thermometer?

Bimetallic thermometer is the use of pressed together when there are differences between the expansion coefficient of metal in the temperature change caused by the different expansion coefficient of deformation produced by the principle of different size, the greater the temperature change, the more serious the degree of deformation will occur in, put it into a pointer value is the thermometer. What are the benefits of using bimetallic thermometer? Actually this is from the bimetallic thermometer itself, for example, with the glass rod of glass liquid thermometer USES similar, but it can use the machine under the condition of higher strength requirements. WSS series bimetallic thermometer is a kind of field detection instrument of proper measurement, low temperature, can be used to directly measure the temperature of the gas, liquid and steam, the thermometer from planning principle and layout is waterproof, prevent corruption, seismic, intuitive, easy reading, no mercury pollution, sturdy and durable, etc. Can replace other industrial thermometer, throughout applied in kerosene, chemical industry, machinery, ships, electricity, textile, printing and dyeing and other industries and scientific research.
