Product Description
Thermostatic bimetal functions:
The effects of thermostatic bimetal curvature in response to a change in temperature are utilized in practical applications to achieve different aims. These can essentially be described by the following functions: Measuring, limiting, controlling, compensation, pulse-generation, retardation. All these functions overlap to a certain extent so that a particular application may fall under several categories.
Measuring
Temperatures and certain electrical variables and their rate of change can be regulated by calibrated systems.
Examples:
Spiral thermometers, Ammeters
Limiting
Trip functions are required at certain upper or lower limits in order to initiate or to cut out an operation.
Examples:
Automatic circuit breakers
Motor protection switches
Controlling
Within a certain range, functions are cut in or out, or circuits made or broken, in order to maintain a certain average setting.
Examples:
Electric iron controls, Bypass valves
Compensation
A deviation from the initial condition is compensated for by the thermostatic bimetal action.
Examples:
Color television tube compensation, Measuring instruments with compensation for fluctuations in ambient temperature.
Pulse-generation
An operation is triggered at clocked intervals.
Examples:
Flasher relays, Hotplate heating coils
Retardation
An incoming signal (e. G. Current)will only trigger an operation after a defined delay period.
Example:
Thermal relay
Bimetal disc also can be toy, it's said by my one of customer that the bimeal jumping disc is very popuar 30 years ago in UAS!
Why does the disc jump?
How it works!
The jumping disc is made from a special piece of metal, called bi-metal that moves when heated with your thumb. When it is warmed to about body temperature, you can "click it" into its loaded position and then carefully place it on a hard surface. When it cools down to room temperature, it suddenly snaps back into the old position, and simultaneously jumps high up in the air. It jumps several hundred times its own height.
The jumping disc works on the same principle as a thermostat or a shunt-valve in your car. With such a thermostat or automatic valve, a special piece of metal, called bi-metal, moves when heat is applied or removed. Bi-metal is actually two pieces of thin metal fused together in the middle. When the temperature changes, the metals expand differently and bend into a curve in either direction.
For instance, when the temperature drops in your home the bi-metal in your thermostat cools down, moves a little, hits a contact and turns on a heater. This way the temperature stays the same. In a car, the metal disc made of bi-metal opens or closes the valve to the radiator, so the water stays about the same temperature to make the engine run well.
In the case of the jumping disc, the bi-metal stays in one position when at room temperature, and in another position when at body temperature. First you warm it to body temperature in your hand, and then you snap the disc between your fingers so it stays in this "new" position. Now you carefully, and quickly, slide it onto a hard surface, like a table. In a few seconds the disc cools off, suddenly snaps back into the regular position, and with a loud "click" flies high into the air!

Company Introduction:
Wuhu Boton Automobile Parts Factory is a professional thermostat manufacturer. We specialize in producing four series of products: Bimetal thermostatic coil and disc, heating chambers for engine carburetors, auto generator regulars, various auto glass lifter motor protectors.
Bimetal thermostat consists of two metallic strips, and this part being adjusted the angle causing movement by the hotter temperature, when heated up, it bends in a pre-determined manner, and can be used to monitor, measure and regulate temperature.
Its main application are in thermostats for heating chamber or fan clutch, but they are also used in control devices for instance in automobiles.
