The pressure transmitter HDA 4000 hazardous rated version has been especially developed for use in potentially explosive atmospheres and is based on the standard HDA 4000 series. As with the industry model of the HDA 4000, devices with hazardous approvals have a proven, fully welded sensor cell with a thin-film strain gauge on a stainless steel membrane without internal seal.

Intended fields of application are, for example, in the oil and gas industry, in mining, on gas turbines or in locations with high dust contamination, e.g. in mills.
