The pressure transmitter series HDA 4400 has been specially developed for measuring tasks with hydrogen. The transmitters are based on a robust, long-life sensor cell with a thin-film strain gauge on a stainless steel membrane. The sensor cell is welded to the process connection, there are no internal seals. The compatibility with hydrogen is ensured by using a particular material. All hydrogen-wetted parts are made of stainless steel 1.4435 with a Ni content of ≥ 13 %.

The pressure transmitters are applicable in potentially explosive atmospheres, and for this purpose, they are approved for the ignition protection types "intrinsically safe" and "non-sparking" according to ATEX and IECEx.
