Bimetallic thermometer is a kind of field measuring instrument for measuring medium and low temperature. It can directly measure the temperature of liquid vapor and gas medium within the range of -80℃-+500℃ in various production processes. ◆ the main features of the on-site display temperature, intuitive and convenient, anquan reliable, long service life; The core-pulling thermometer can be stopped for short time to maintain or replace the movement. Axial type, radial type, 135 type, universal type and other varieties, suitable for a variety of field installation needs.

Bimetallic thermometers are based on bimetallic plates that are wound in a tortuous fashion. When one end is expanded by heat, the pointer is rotated and the work meter shows the temperature value of the thermoelectric potential.

◆ working principle

Thermal resistance is the measurement of temperature by means of the characteristic that the resistance of a substance varies with its temperature. When the resistance value changes, the work meter displays the temperature value corresponding to the resistance value.
