How many types of bimetal sensors and their explanation?

Bimetal sensors typically come in two main types: bimetallic temperature sensors and bimetallic pressure sensors. Bimetallic temperature sensors consist of two different metals bonded together that expand at different rates when heated, causing bending that can be used to indicate temperature changes. Bimetallic pressure sensors use the deflection of a bimetal strip to measure pressure variations, converting mechanical movement into an electrical signal. Both types are widely utilized for their reliability and accuracy in various industrial applications.
