application
Bimetallic thermometer is a kind of measurement in the field of low temperature test instrument. Can be directly measured in the process of various production - 80 ℃ to + 500 ℃ within the scope of liquid steam and gas medium temperature.
The main features
The scene display temperature, intuitive and convenient
Safe and reliable, long life;
Core-pulling thermometer can not stop short time machine maintenance or replacement.
Axial, radial and 135 DHS type, universal type variety complete, suitable for all kinds of the needs of the installation.
The working principle of
Bimetallic thermometer is based on the ring around the made of bent bimetallic strip. End is heated expands, turns the pointer, the instrument will show thermoelectric potential should value.
