HDA 4700 Electronic Pressure Transmitters ATEX Intrinsically safe

The pressure transmitter HDA 4700 in ATEX version has been specially developed for use in potentially explosive atmospheres for absolute measurement in the low pressure range and is based on the HDA 4000 series.

As with the industry model, the ATEX version HDA 4700 has a ceramic measurement cell with thick-film strain gauge.

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