Description

 

Thermal bimetallic layer is composed of two layers with different linear Solid combination of expansion coefficient of metal composite materials.It holds the higher thermal sensitivity and high resistivity, low temperature stability is good, the welding is more easily and widely used. And it mainly is used for temperature measurement and automatic control equipment in the thermal sensitive element.
