Hydac Electronic Pressure Transmitter HDA 4700 with Flush Membrane

Hydac Electronic Pressure Transmitter HDA 4700 with Flush Membrane

Pressure transmitter HDA 4700 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 4700 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 ≤ 0.25% FS typ
• Highly robust sensor cell
• Very small temperature error
• Excellent EMC characteristics
• Very compact design
