Delta Controls’ full range of Sentry pressure, differential pressure and temperature switches is now available in ATEX and IECEx Flameproof versions.

Approved for use in Zone 1 and Zone 21 hazardous areas, the high quality switches are suitable for use in sectors such as oil and gas and petrochemicals.

Based on the company’s popular Sovereign series, the Flameproof switches are competitively priced and offer better than one percent set point repeatability. The switches also come with a ‘market leading’ five-year warranty, Delta Controls explains.

Designed for ease of use, the compact units are smaller and lighter than earlier models. 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 0-350degC. Like other Delta Controls products, they can be adapted to suit customer requirements.

Delta Controls operates with locations in the US, UK, Italy, China and Malaysia.
