Is the pressure switch the same as the pressure controller?
The original world really nothing is forever. A friendship, left on the light. A love, separated on the scattered. Now have, and perhaps the next second, no longer belong to you.
Some of the pressure switches are fixed pressure values, some are adjustable pressure values. Usually can not be called the pressure switch, adjustable called pressure controller.
Pressure switch is generally composed of "pressure element bellows + action mechanism + electrical contact" and other components, the principle is to feel through the pressure and produce a small movement, the action switch to the circuit. It is called pressure switch.
Personally think that the pressure controller can also be a pressure switch, but also can be used to stabilize the pressure components, such as diaphragm pressure regulator, regulator valve.
The key question is: look at the component is the pressure control circuit, or stabilize somewhere the pressure, which is the essence of the problem. (Answer: QQ users - Energy Star)
