Thermostat Bimetallic Strip 5J1580 for Temperature Instruments / hygrothermograph

Precision Alloy Thermostat Bimetallic Strip 5J1580 for Automatic Control Devices and Instrumentation

Name: 5J1580/ Kanthal 155/ ТБ 1523

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 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.

Standard: GB/T 4461-1992
