Hydac Electronic Pressure Transmitter HDA 4400 with Flush Membrane
The HYDAC HDA 4400 with Flush Membrane is a compact, high-accuracy pressure transmitter designed for applications where clogging or contamination is a concern. Its flush stainless steel membrane prevents blockage and ensures reliable measurement in demanding or frequently changing media environments.
Key Features:
- Flush stainless steel membrane prevents clogging and contamination
- High accuracy (≤ ±0.5 % FS) with minimal temperature drift
HYDAC Electronic Pressure Transmitter HDA 4400 with Flush Membrane
Pressure transmitter HDA 4400 with a flush membrane was designed specifically for applications in which a standard pressure connection could become blocked, clogged or frozen by the particular medium used. Further applications include processes where the medium changes regularly and any residues could cause mixing or contamination of the media.
Like the standard model, the HDA 4400 with flush membrane has a stainless steel measurement cell with a thin film strain gauge for relative pressure measurement in the high pressure range.
The pressure connection is achieved with a fully-sealed stainless steel front membrane filled internally with a pressure transfer fluid. The process pressure is transmitted hydrostatically to the measurement cell via the pressure transfer fluid.
The output signals 4 .. 20 mA or 0 .. 10 V enable connection to all HYDAC measurement and control devices as well as connection to standard evaluation systems (e.g PLC controls).
Special features:
- Pressure connection has a flush membrane
- Accuracy ≤ 0.5% FS typ
- Highly robust sensor cell
- Very small temperature error
- Excellent EMC characteristics
- Very compact design
