Bimetallic Thermometer

Application
Bimetallic thermometer is a local measurement instrument for low medium temperature, widely used for directly measuring liquid, steam and gas, ranged from -80℃ to +500℃.

Operating Principle
It is manufactured from two cold-welded metal strips with different thermal expansion coefficients and rotates in proportion to temperature. The rotary movement is conveyed to the pointer with low friction.
