Bimetallic thermostat quality judgment
Currently bimetallic thermostat on the market price is very confusing, Unit price difference is very big. The main factors affecting the unit price of the product, Is the product quality, So how to determine the quality of the thermostat it? This first need to understand the basic principles of the thermostat. We use sudden jump KSD301 (KSD9700) Thermostat example:
Sudden jump KSD301 (KSD9700) Thermostat works:
KSD301 thermostat is the use of disc-type bimetal as a temperature sensing element. When the temperature rises to the set value, Bimetallic discs sudden jump, Drive contact rapid action, Off / on circuit. When the temperature drops to the set value, Bimetal disc reset, Contacts also will be restored to its original state, On / off circuit, To achieve the purpose of electrical temperature protection.
KSD301 (KSD9700) Thermostat quality related indicators:
1>. Thermostat life is the key:
Thermostat life on the need to take into account two aspects of the key components,
One: is bimetal, Different temperature of the life of the film will be very different, Of course, prices vary widely,
Second, is the contact, The on-off of the temperature-controlled switch is realized by the contact and disconnection of the contact, So touch the need to be able to withstand a certain current and voltage of the material and material thickness, Current market contacts are copper and silver, Silver contacts energized performance will be much better.
2, the thermostat itself fever: the current temperature control of the internal material using copper, Different copper material itself is different from the heat, If the use of the material heat large, It will affect the bimetal temperature accuracy. If no current thermal effect of material, Thermostat temperature accuracy will be more accurate, Longer life.
3>, the thermostat temperature speed:
This need to match the power and heating appliances, The greater the power the faster the heat. It will need to calculate the thermostat temperature time, The correct choice of the temperature controller temperature segmentation, Thermostat will have a sense of temperature fast, quick action, No arc characteristics.
4>. Thermostat installation:
KSD301, KSD9700 thermostat temperature is by sealing the surface of the aluminum cover. Passed to the thermostat internal air, Or through the aluminum lid radiant heat to the temperature of the body, Then the installation is to make the product close to the installation surface of the controlled device. If the product is not installed correctly, Also will not affect the thermostat performance, The correct installation method, please refer to my company's product specifications
5>. Thermostat electrical characteristics: When the thermostat installed in some of the voltage and current sense of heat compared to electrical appliances, Then you need to consider the electrical electrical problems, The best choice of normal electrical strength: 50Hz, 2000V, 1m without breakdown or flash-way thermostat switch.
Bimetal thermostat quality judgments contain many factors, Specific quality impact, Please consult our company technicians, I will give you a detailed description of the company.
