Bimetal disc thermostats series is a small-size bimetal thermostat series with a metal cap,which belongs to thermal relays family. The main principle is that one function of bimetal discs is snap action under the change of sensing temperature. The snap action of disc can push the action of the contacts through the inside structure, then caused on or off of the circuits finally. The main characteristics are the fixation of working temperature, the reliable snap action, less flashover, longer working life and less radio interference
The bimetal in bimetal disc thermostats are made by pressing two metals with very different thermal expansion coefficients together. At different temperatures, the difference in the deformation of the metal on both sides causes the bimetal to bend. Use this deformation to Push the quick mechanism to drive the switch contacts to close and open.
The bimetal disc thermostats are more accurate for the temperature control of the electrical appliances used, has excellent functions, simple production process, low cost, and wide range of uses, so it is very popular. Our users are generally not aware that there is such a small device in the electrical appliances they use. Even if there is a problem, the repair and replacement are very simple, and the cost is quite low
Main applications of bimetal disc thermostats :
1.Temperature control of the electric apparatuses like water heater, frier, cylinder washing machine, electrical boiler, sealing machine, subterrene, steak stove, and commercial freezer etc.
2.Roti maker, Toaster Oven, Electrical Stove , Rice Cooker, Heater
3.Barbeque grill and various household appliances.
