This pressure transmitter has been specially developed for shipbuilding applications and is based on the HDA 4000 series.

The HDA 4400 is designed to measure relative pressures in the high pressure range by means of its sensor measurement cell with thin-film strain gauge on a Stainless Steel membrane.

The evaluation electronics converts the measured pressure into a proportional analogue signal of 4 .. 20 mA. The electronic module is completely potted to protect it against humidity, vibrations and shock, and is enclosed in a solid Stainless Steel housing.
