Thermostatic Bimetal Strip 1mmx5mm Telcon200 For heat-sensitive
components
Common Name: 5J20110, Telcon200, 1200,ASTM B388 TM2
Application area:
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 changes, resulting 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 bonded, having a temperature-dependent shape change occurs thermosensitive
functional composites.Wherein the higher expansion coefficient of the active layer is a layer called a low coefficient of expansion of the layer is named passive layer.
