Product Description

Tankii thermal Bimetal strip TB140/80 in 6.0mm width X 1.0mm thickness

A bimetallic strip is used to convert a temperature change into mechanical displacement. 
The strip consists of two strips of different metals which expand at different rates as they are heated. 
The different expansions force the flat strip to bend one way if heated, and in the opposite direction if cooled below its initial temperature. 
The metal with the higher coefficient of thermal expansion is on the outer side of the curve when the strip is heated and on the inner side 
when cooled.

Main features: Linear temperature range is higher, low thermal performance, can be used at middle temperature.
