Understanding Pressure Switches
Pressure switches are essential components in fluid-handling systems‚ acting as the control mechanism for pumps‚ compressors‚ and other equipment. They function by sensing the pressure within a system and triggering an electrical signal based on predefined pressure levels. This signal can then activate or deactivate pumps‚ compressors‚ or other devices‚ ensuring that the system operates within desired pressure ranges.
A pressure switch typically comprises a sensing element‚ a diaphragm or piston‚ that responds to pressure changes within the system. This change in pressure causes the sensing element to move‚ activating an internal switch mechanism. The switch mechanism‚ usually a set of electrical contacts‚ closes or opens an electrical circuit‚ initiating or terminating the operation of the connected equipment.
Pressure switches are characterized by two key pressure settings⁚ cut-in pressure and cut-out pressure. Cut-in pressure refers to the pressure level at which the switch activates‚ turning on the pump or compressor. Cut-out pressure‚ on the other hand‚ represents the pressure level at which the switch deactivates‚ shutting off the pump or compressor. The difference between these two pressure settings is known as the differential pressure‚ which determines the pressure range within which the system operates.
