Bimetallic thermometer and other thermometer compared advantage characteristics

Bimetallic thermometer concept: the bimetallic thermometer is a kind of measuring instrument in the field of low temperature detection, mainly for various dielectric measurements, such as gas, steam, liquid is widely used in many fields. Bimetallic thermometer temperature measurement principle, bimetallic thermometer is a round shape into threaded heat bimetallic strip as thermal devices, and put it in a protective sleeve tube, one end is fixed, known as the fixed end, the other end of the connection on a thin shaft, a free end. Spool at the free end is equipped with a pointer. When the temperature changes, the resulting thermal devices the free end of the rotation, drive the thin axis from the Angle of the pointer changes, corresponding temperature indicator on the dial. Bimetallic thermometer features: 1. Compared with the mercury thermometer mercury-free harm 2. Easy to use, long service life. 3. Application range is wide, temperature measuring range is usually - 80~600℃4. Compared with the electronic thermometer without energy
