The overview and working principle of bimetallic thermometer

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 the waterproof, anti-corrosion, explosion-proof, resistant to vibration, intuitive, easy reading, no mercury pollution, strong and durable and so on. Can replace part of the measuring instrument, widely used in petroleum, chemical industry, machinery, ships, electricity, textile, printing and dyeing and other industrial and scientific research departments. Bimetallic thermometer working principle is to use two different temperature expansion coefficient of metal, welding in fixed point at one end, on the other side when temperature distortion, converts it into a pointer deflection Angle, indicating the temperature. Core pulling type refers to bimetal thermal element can change from the external protecting tube, is the most widely used field indicating thermometers. We can according to their own needs, install and use, environment, choose suitable for bimetallic thermometer, please note that at the same time, the bimetallic thermometer should be timely clean after use, should arrange verification on a regular basis.
