YUNYI bimetallic thermometer

Mechanically Reliable · Intuitive and Durable — The Classic Choice for Industrial Temperature Measurement

YUNYI bimetallic thermometer is a mechanical temperature measurement instrument based on the thermal expansion principle of a bimetallic strip. Its core component is a spiral or helical bimetallic strip composed of two metals with different coefficients of thermal expansion. When temperature changes, the differing expansion rates of the two metals cause the bimetallic strip to bend. This deformation drives a pointer via a transmission mechanism to indicate the corresponding temperature value. Requiring no power source, featuring a robust construction, and providing intuitive readings, this product serves as the most economical and practical on-site temperature indicator for various industrial applications.
