At higher temperatures bimetallic thermometer pointer in which direction will turn?

Bimetallic thermometer is a common scene temperature measuring meter, it is also called pointer thermometer, piping, hvac, industrial thermometer thermometer thermometer, etc. Common bimetallic thermometer is as follows: when the temperature rises bimetallic thermometer pointer in which direction will the rotation? Let's look at the working principle of the bimetallic thermometer is a thermal device is composed of two layers of linear expansion coefficient difference is relatively large pieces of metal welded together, one end of the element as the fixed end, on the other side of the free end. When the temperature changes, because the bimetallic strip of material is different, linear expansion coefficient of relatively large differences, and produce different expansion and contraction, leading to the curving deformation of bimetallic strip, equipped with actuator (at the free end Dial pointer and temperature) So that it can directly show the temperature value. Dial from low to high temperature is clockwise design thus, when the temperature rises, the bimetallic thermometer pointer will move to the right ( Clockwise) Rotation. Actually not only bimetallic thermometer, pressure type thermometer and so on.
