Application and selection of bimetallic thermometers

A bimetallic thermometer is an on-site detection instrument used to measure low to medium temperatures. Bimetallic thermometers can directly measure the temperature of liquid, vapor, and gas media within the range of -80 ℃ to+500 ℃ in various production processes.

feature：

On site temperature display, intuitive and convenient;

O Safe and reliable, with a long service life;

Multiple structural forms can meet different requirements.

working principle：

A bimetallic thermometer is composed of bimetallic sheets wound in a circular curved shape. When one end is heated and expands, it drives the pointer to rotate, and the working instrument displays the corresponding temperature value.
