Thermocouple and bimetallic thermometer compare their advantages is what

Thermocouple and bimetallic thermometer between the two is very close, just at the time of measurement temperature, bimetallic thermometer is suitable for use in the detection of low temperature state of the scene, in the process of measurement can measure the gas medium of minus eighty degrees Celsius to five hundred degrees Celsius temperature and the temperature of the liquid vapor, mostly used in high temperature industrial thermocouple, while in low temperature environment is the use of bimetallic thermometer is reasonable, and the main components of bimetallic thermometer is carried out by one or more metal overlap of multilayer metal plates, using their swelling degrees of different in different temperature as a principle of work, when one end is after thermal expansion occurs, pointer will be driven to rotate, the instrument will show on the corresponding temperature value.
