PLN934 Lovato PRESSURE SWITCH

Why Choose the Lovato PLN934 Pressure Switch?

The Lovato PLN934 is a special pressure-operated switch designed for industrial pressure monitoring and control applications. Classified within Lovato Electric's range of limit, micro and foot switches, it provides an electromechanical switching function that can be incorporated into equipment where a change in pressure must initiate an electrical control or signalling action.

The PLN934 provides 1 normally open + 1 normally closed (1NO + 1NC) contact functions, allowing complementary electrical signals to be generated when the pressure-operated mechanism changes state. This makes the switch suitable for control, indication, interlocking and monitoring functions in appropriately designed pressure systems.

The PLN934 is also documented as the limit-switch element used within specialised pressure-switch assemblies for fire-extinguishing equipment. In such assemblies, the pressure-operated mechanism converts a mechanical pressure change into an electrical contact change, allowing connected control equipment to detect system operation or pressure status.

Electromechanical Pressure Monitoring and Signalling

Pressure switches are used to translate a defined mechanical pressure condition into an electrical switching signal. When incorporated into a compatible pressure-operated assembly, the Lovato PLN934 can provide both normally open and normally closed contact functions, allowing connected equipment to respond to a change in pressure state.

The 1NO + 1NC arrangement provides flexibility for applications requiring simultaneous signalling and control functions, such as changing an indicator state while also supplying a signal to a controller, relay or monitoring circuit. The PLN934 should be installed as part of an appropriately engineered pressure-control assembly suited to the required operating conditions.
