Bimetallic thermometer and the application scope of works is?

Bimetallic thermometer is a kind of field detection instrument suitable for the measurement of low temperature, and can be used to directly measure the temperature of the gas, liquid and steam. The thermometer from the design principle and the structure has a waterproof, anti-corrosion, vibration resistance, intuitive, easy reading, no mercury pollution, strong and durable, etc. Is widely used in petroleum, chemical, machinery, ships, electricity, textile, printing and dyeing and other industrial and scientific research departments. Commonly used temperature range is as follows: structural characteristics and working principle of bimetallic thermometer is made of round shape into threaded heat dual metallic piece as temperature sensing element, and put it in a protective sleeve, one end fixed ( Fixed end) And the other end, The free end) Connection on a thin shaft, shaft end is equipped with a pointer. When the temperature changes, temperature sensing element of the free end immediately rotation, thus fine axis pointer to produce angular displacement, indicates that the change in temperature on the dial; Straight table is said to drive gear drive pointer. Due to the heat element linear relationship with temperature changes, so the location of the bimetallic thermometer pointer indicated is measured temperature value.
