Thermostatic Bimetal Spirals
Wuhu Boton Automobile Parts Factory is a professional manufacturer with Boton brand and self-developement capacity. Our core competencies is thermostatic bimetal components, thermometer, jumping disc toys, heating chamber for engine carburetors, auto generator regulars,various auto glass lifter motor protector.
Thermosatic Bimetal Spirals (also called bimetal spring ,bimetallic coil) consists of two or more metallic strips with different thermal expansion bonded together. When heated up, it bends in a pre-determined manner and can be used to monitor, measure and regulate temperature.
Springs of the thermostatic bimetal achieves greater “active length” within a small space, thus maximizing the possible displacement.
One end of the spiral /helical coil is permanently fixed .the loose end describes a rotary path in response to a change in temperature.
The choice between a spiral or a helical coil depends on the intended application.
Spirals are preferred for measuring ambient temperatures (room temperature, sauna thermometer).
