The programmable electronic pressure switch EDS 4400 with flameproof enclosure has triple approval acc. to ATEX, CSA and IECEx which ensures the instrument is universally suitable for use in potentially explosive atmospheres worldwide. Each instrument is certified by the three approvals organizations and is labelled accordingly. Therefore there is no longer any need to stock multiple devices with separate individual approvals.

As with the industry model of the EDS 4400, those with triple approval have a proven, fully-welded sensor cell with a thin-film strain gauge on a stainless steel membrane without internal seal. The instrument is programmed conveniently and simply using the HYDAC Programming Unit HPG 3000.

The main fields of application are in mining and the oil & gas industry, e.g. in underground vehicles, hydraulic power units, blow-out preventers (BOPs), drill drives or valve actuation stations as well as in locations with high levels of dust contamination.
