VOGEL DS-W1-4

VOGEL DS-W1-4 Product Details

The VOGEL DS-W1-4 is a pressure switch designed for monitoring pressure in various applications, particularly within centralized lubrication systems. It plays a crucial role in ensuring the proper functioning of these systems by monitoring pressure build-up and release, the operation of directional control valves (in zoned systems), filter clogging, and potential leaks or air presence in the system.

This pressure switch features a non-adjustable switching pressure, which is factory set. It utilizes a changeover contact element housed in an airtight and distortion-resistant plastic casing that meets UL specifications. The switching action is triggered by a pin connected to a spring-loaded membrane when the set pressure is reached.

The DS-W1-4 is available with different plug versions for electrical connection. It's important to note that when switching off inductive loads, protective circuits like RC elements or varistors can be implemented to limit voltage spikes and extend the lifespan of the contacts. However, incorrect dimensioning of such circuits can be detrimental.
