HYDAC Electronic Pressure Transmitter for shipbuilding and offshore HDA 3400 HDA 3700 HDA 4000 HDA3000 HDA7000 HDA8000

This pressure transmitter, which has been specially developed for shipbuilding and offshore applications, is based on a very
robust DMS sensor cell. All parts in contact with the fluid are in stainless steel, and are welded together.  Since no seals are required
in the sensor chamber, leakage is eliminated. The 4 .. 20 mA output signal in two conductor technique enables connection to the relevant evaluation electronics. Areas of application are pressure monitoring on marine transmissions, diesel engines, pumps and general hydraulic and pneumatic systems.

This pressure transmitter has been specially developed for shipbuilding and offshore applications and is based on the HDA 4000 series. By using ceramic measurement cells, absolute and relative pressure measurements can be made in the low pressure range.  Stainless steel measurement cells are used for measuring in the high pressure range.
The Digital Display Unit HDA 5500 is a microprocessor controlled display and monitoring unit designed for control panel mounting. Different versions are available with a maximum of 3 analogue inputs and 4 relay outputs. The analogue input signals are displayed according to the measuring scale selected by the user. Each of the 4 relay outputs can be allocated to each of the 1 to 3 sensor inputs or to the differential between input 1 and 2. The PT100 temperature probe can be connected directly to the unit. 
The pressure transducer series HDA 4100 is equipped with a ceramic pressure measurement cell with thick-layer DMS, which was specially developed for absolute pressure measurement in the low-pressure range
The The pressure transducer series HDA 4300 is equipped with a ceramic pressure measurement cell with thick-layer DMS, which was specially developed for relative pressure measurement in the low-pressure range.
The pressure transducer series HDA 4400 is equipped with a pressure measurement cell with thin-film DMS on a stainless steel diaphragm.
The pressure transducer series HDA 4700 is equipped with a very accurate and robust sensor cell with a thin-film DMS on a stainless steel diaphragm.
The pressure transducer series HDA 4800 is equipped with a very precise and robust sensor cell with a thin-film DMS on a stainless steel diaphragm.
The pressure transducer series HDA 7400 unites outstanding technical data with very small, compact installation form.
The pressure transducer series HDA 8400 was specially developed for series utilisation, e.g. in mobile applications.
The pressure transducer series HDA 8700 was specially developed for series utilisation, e.g. in mobile applications.
The pressure transmitter series HDA 9000 has been specially developed for low pressure applications in the industrial and mobile sectors. The transmitters are available in various pressure ranges from 0 .. 1 bar to 0 .. 100 bar. For integration into modern controls,
standard analogue output signals are available, e.g. 4 .. 20 mA,  0 .. 5 V, 1 .. 6 V or 0 ..  10 V. Ratiometric output signals are also
available.  For the electrical connection, different types of integrated connections are available. A  typ.,combined with a small temperature drift, ensures a broad range of applications for the HDA 9300, e.g. in pump and compressor controls, refrigerating
plants and air conditioning, or for pilot controls in the mobile sector.
