Functional Description

Preferably for applications in marine business / ship industry these pressure
transmitters were designed based on standard HDA 4000 series.
Featuring ceramic sensor cells, absolute and relative pressure in low pressure
applications are measured. For measurements in high pressure applications stainless
steel sensor cells are used.
The electronic circuits with HYDAC-ASIC proportionally change pressure readings into
a 4..20 mA analogue signal. To protect against moisture, vibration, and shock the
electronics are fully encapsulated and put in a solid stainless steel housing.
For the use in ship industry the following companies have approved the HDA 4000:
