About HDA 4000 Pressure Transducers:
Preferably for applications in marine business / ship industry, these pressure transmitters were designed based on the 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 to 20 mA analogue signal. To protect against moisture, vibration, and shock the electronics are fully encapsulated and put in a solid stainless steel housing.
Every pressure transmitter HDA 4000 series is calibrated on computer-controlled test rigs and submitted to a final test. The pressure transmitters do not require any maintenance and operate satisfactorily when used according to their specifications (see technical details). In the case of any unsatisfactorily operation, please contact HYDAC Service. Interference from anyone other than HYDAC personnel will invalidate all warranty claims.
