1mmx5mm Thermal Bimetallic Strip 5J20110 Grade For Spring
1mmx5mm Thermal Bimetals Strip 5J20110 For Spring
Application:This material is mainly used for automatic control devices and meters (such as: exhaust thermometer, thermostat, voltage regulator, temperature relay, automatic protection switch, diaphragm meter, etc.) as temperature control, temperature compensation, current limiting, temperature indicator and other thermal sensing elements.
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.
