A range of high quality process industry switches has been introduced by Delta Controls. The Sentry range consists of pressure, differential pressure and temperature switches and is based on the company’s popular Sovereign series.
The new competitively priced switches offer better than 1% set point repeatability and come with a five-year warranty.
Switch enclosures are protected by a novel hinged lid with a single captive screw which allows quick access to terminals and for set point adjustment. A safety vent protects users by eliminating the risk of the enclosure becoming pressurised if the sensor were to suffer damage from pressure overload.
As well as for general applications, the Sentry range is available with ATEX/IECEx Intrinsic Safety approval for use in Zone 0 hazardous areas, making them suitable for sectors such as oil and gas and petrochemicals.
The switches are available with SPDT or DPDT contacts, with an optional hermetically sealed configuration. The epoxy coated aluminum enclosure provides environmental protection to IP66/NEMA 4X. The pressure switch range covers 0-700 bar, the differential pressure range is 0-10 bar and the temperature switch range is 0-350ºC.
