Preset pressure switches are sealed to
IP67
A new range of preset pressure switches feature an integrated M12 connector and offer a sealed design protected to IP67.
A new range of preset pressure switches feature an integrated M12 connector and offer a sealed design protected to IP67 Available for pressures from 0.2 to 300bar, the new switches provide inherently reliable operation in highly demanding applications where even IP65 protection is not enough to ensure long term reliability of the switch or, in extreme situations, the assured operation of the connected circuitry

The SmartScan range of ultrasonic continuous solid and liquid level measurement instruments is suitable for use in process tanks and storage vessels.
The new MS/PS pressure switches with integrated M12 plug extend one of world's largest ranges of fluid control products, and have been developed in response to increasing market demand for a rugged, compact, preset item with IP67 protection.
The design integrates a 4-pin M12 connector into a newly developed protection cap to provide a product that guarantees high integrity while making installation quick and easy.
The IP67 MS/PS pressure switches will be of particular interest in mobile plant applications that face extreme environmental conditions beyond the sealing capabilities of even IP65 protection.

Level switch upgrade handles high pressures
PVL supplies all the flanges, gaskets and fitting kits to make replacement of Solartron Mobrey level switches straightforward.
The new switches will also provide a more reliable solution in damp or dusty industrial situations, or in the likes of machine tool applications where cutting oils are an ever-present problem and where IP65 protection is simply not enough, Further, the new switches should also provide increased assurance of operation in applications where the pressure switch is connected to solid state control equipment, as PVL's Steve Moorey explains: "The increased usage of solid state control equipment can make life a bit difficult for the pressure switch.
The high currents associated with electromechanical switchgear help to keep the contacts of the pressure switch clean, but the currents through solid-state devices are too low to have any effect.
Gold-plated contacts in the pressure switch obviously help, but even so it can only take a few molecules of dirt seeping in through the seal to build up on the contacts before operation is compromised.
The IP67 design effectively eliminates the problem".
The IP67 MS/PS range is available in a huge range of options, covering adjustment ranges from 0.2 to 300bar, different diaphragm and piston seal materials, choice of body materials, a wide choice of thread connections, preset switching on rising or falling pressures, and high pressure or degreased execution.
The result is a highly flexible and versatile range of products that will meet the needs of the widest possible range of applications.
MS/PS pressure switches provide a single-pole, double-throw (SPDT) contact configuration, rated at 250V AC, 3A.
They also provide a specific pin for ground connection, to assure the highest levels of safety whatever the application. Request a free brochure from PVL ...
