P70R Thermal Bimetal Strip For Controller Switch 0.12 Resistivity

P70R Thermal bimetal alloy strip

overview
 

Thermal bimetal strip,which is solid combined along the whole contact surface with two or more layers of metal with different expansion coefficient, is thermo sensitive functional composite material 

Thermal bimetal strip is by the different expansion coefficient of two or more than two layers of metal or metal solid combination, and along the entire interface varies with temperature and the thermal function of shape changes in composite materials.One of high expansion coefficient become active layer, low expansion coefficient becomes passive.When requirements with high resistivity, but heat sensitive resistance performance is essentially the same type of thermal bimetal series, can be added between the two layers of different thickness of middle layer as a shunt layer, is to achieve the purpose of control different resistivity.

The basic characteristic of the thermal bimetal is changing with temperature and temperature deformation, resulting in a certain moment.Many devices use this feature to convert heat energy into mechanical work to achieve automatic control.Thermal bimetal used for control system and temperature sensor in the measuring instrument.

Main features: Linear temperature range is higher, low thermal performance, can be used at high temperature.
