Excellent long-term properties The pressure transmitter HDA 4700 in IECEx Intrinsically Safe version has
been especially developed for use in
potentially explosive atmospheres and is based on the HDA 4000 series. As with the industrial version of the HDA 4700, devices with IECEx Intrinsically Safe approval have a field-proven, all-welded stainless
steel measurement cell with thin-film strain gauge without internal seal. The pressure connection is achieved with an all-welded stainless steel front membrane filled internally with a pressure transfer fluid. The process pressure is transmitted
hydrostatically to the measurement cell via the pressure transfer fluid. This device is used for applications
in which a standard pressure connection could become blocked, clogged or frozen by the particular medium used. Further applications include processes where the medium changes regularly and any residues could cause mixing or contamination of the media, or in highly viscous media. Intended areas
of application are, for example, the oil
and gas industry, in mines or in locations
with
high levels of dust, e.g. in mills.
