PRESSURE SWITCHES

Adjustable pressure switches are electromechanical devices used to control pressure in hydraulic, pneumatic and water circuits. Adjustable pressure switches switch when a pressure (rising or falling), determined during calibration, is reached. When this pressure is reached, they switch the state of the electrical contact inside them.

The main features of adjustable pressure switches are:

System protection: when the set threshold is reached, they switch pumps, valves or other devices on or off, ensuring system stability. They prevent overpressure or excessive pressure drops, preventing damage to hydraulic components.
Operational flexibility: they allow the activation and deactivation threshold to be set according to the specific needs of the system.
Application versatility: used in sectors such as hydraulics, industrial automation, agriculture, automotive and air conditioning systems.

Thanks to their adjustable set-point, these pressure switches represent an essential solution for pressure control, guaranteeing reliability and efficiency in the most diverse industrial contexts.

Pressure switches - General information and Operating principle

The adjustable pressure switches are used in control systems, where at project level it is useful or necessary to obtain a change of electric state at a specific pressure value. Common applications of pressure switches are in the safety systems of hydraulic and pneumatic brake systems of convoy vehicles, trains, road trains, or air compressor, hydraulic circuits etc...
