Thermostat manufacturing principles

Thermostat according to the manufacturing principles can be divided into:
1. A sudden jump thermostat
the various sudden jump thermostat model collectively referred to KSD, such as the common KSD301 KSD302 thermostat bimetal thermostat new products, mainly as a variety of electric product with overheat protection, usually used in series with the thermal fuse, as a sudden jump-temperature protection. Thermal fuse in the sudden jump-temperature loss of Lou failures have led to over-temperature of the heating element, as a secondary protection from effectively prevent burn out the heating element and the resulting fire accident.

2. The liquid up thermostat
When the temperature changes of the object to be controlled so that the temperature sensing portion of the thermostat within the substance (usually liquid) to generate a corresponding expansion and contraction of the physical phenomenon (volume change), together with a film cartridge in communication with the temperature sensing portion expands or contraction.Lever principle to drive the switch-off action, to achieve the purpose of constant temperature. Liquid expansion thermostat has the following performance characteristics of temperature control accurate, stable and reliable, small temperature difference between open and stop, wide temperature adjustment range, the overload current.Fluid up thermostat temperature control applications with mainly used for household appliances, electric equipment, refrigeration industry.

3. Pressure type thermostat
Bulb and capillary filled temperature sensing qualitative change the thermostat in a closed, controlled temperature changes into the space pressure or volume changes, when the temperature setpoint is reached, through the elastic element and the fast instantaneous institution automatically close contact, in order to achieve the purpose of automatic temperature control.It is Composed of  the temperature sensing portion, the temperature main body portion, to perform the jog switch or the automatic throttle opening and shutting.Pressure type thermostat suitable for refrigerating appliances (such as refrigerators, freezers, etc.) and heating and other occasions.These are the most common temperature controller type, of course, can also be divided by use classification to floor heating thermostat, air conditioning thermostat, motor thermostat, the thermostat uses very difficult to generalize, It is not accurate to classified the thermostat according to use, often have the phenomenon that a thermostat with different names.

4. Electronic thermostat
The electronic temperature controller (resistive) is measured using the method of the resistance temperature sensing, commonly used the platinum wire, copper, tungsten, and the thermistor as the temperature measuring resistor, indeed point of these resistors has its advantages. Most of the typical home air conditioning thermistor.
