What are the types of bimetallic thermostat? Introduction to the characteristics of each type of bimetallic thermostat

Bimetallic thermostat is a kind of temperature sensor, which is widely used in water heater, water dispenser, soybean milk machine, refrigerator, air conditioner and other household appliances. Bimetallic temperature controller has the advantages of small volume, light weight, high precision, long service time and small radio interference. There are many kinds of bimetallic temperature controller. At present, there are mainly three kinds of contact action.

Bimetal thermostat

Slow acting temperature controller has high sensitivity and ideal temperature control. However, when the temperature is close to the on-off temperature of the temperature controller, the pressure of the dynamic starting point may drop, resulting in poor on-off and arcing. If this happens many times, the contact will be oxidized, and if it is serious, there may be adhesion. Slow motion temperature controller appeared earlier, can be divided into two kinds, that is, the temperature can be harmonic temperature setting. The situation of temperature control is not the same, so the principle used in the work is not the same, so there are some differences in the effect.

Compared with the slow-moving thermostat, the flashing thermostat is a new type, which makes up for the disadvantages of the slow-moving thermostat to a great extent. Scintillation temperature controller can be divided into two types: temperature and temperature setting. This kind of temperature controller is very fast when the contact is on and off, there will be no arcing, and the accuracy of temperature control is relatively high. The pressure between the contacts is relatively large and the resistance is relatively small, so it is not easy to damage. It is used for a longer time and has little interference to radio.

Jump type temperature controller is one of the three more new, its performance characteristics are better than the first two, the current range of use is more extensive, general household appliances, industrial appliances, can be used, and play a great role. Jump type temperature controller can be divided into open type and sealed water type, which are used in different electrical appliances.

Bimetallic temperature controller for the use of electrical temperature control is more accurate, excellent use function, production process is relatively simple, low cost, wide range of uses, so it is very popular. Our users generally do not know that there is such a small device in their own electrical appliances. Even if there is a problem, the maintenance and replacement are very simple, and the cost is quite low.
