Product Overview >
Apply
Bimetal thermometer is a kind of field instrument for measuring medium and low temperature. It can directly measure the temperature of liquid, steam and gas medium in the range of -80℃~500℃ in various production processes.
peculiarity
On-site temperature display, intuitive and convenient;
Safe and reliable, long service life;
A variety of structural forms to meet different requirements.
Working principle
Bimetallic thermometers are based on a bimetallic sheet wound into a circular bending shape. When one end is expanded by heat, the pointer is rotated, and the working instrument displays the temperature value corresponding to the thermoelectric potential.
