Application: The material is mainly in automatic control devices and instrumentation (eg: exhaust thermometers, thermostats, voltage regulators, temperature relay, automatic protection switching, diaphragm meters, etc.) make temperature control, temperature compensation, current limit, temperature indicator and other heat-sensitive components.

 

Feature: The basic characteristics of Thermostat Bimetallic is bending deformation with temperature changesresulting in a certain moment.
Thermostat Bimetallic Strip expansion coefficient is different from the two or more layers of metal or alloy along the entire contact surface firmly bondedhaving a temperature-dependent shape change occurs thermosensitive functional compositesWherein the higher expansion coefficient of the active layer is a layer called a low coefficient of expansion of the layer is named passive layer.
