Hydac Electronic Pressure Switch Type EDS 4400 - Programmable

• Measuring ranges: 40; 100; 250; 400; 600 bar
• Overload pressures: 80; 200; 500; 800; 1000 bar
• Burst pressures: 200; 500; 1000; 2000; 2000 bar
• Mechanical connection: G1/4 A DIN 3852
• Torque value: 20 Nm

The following parameters can be changed:

• Switching point
• Hysteresis
• Switching direction (N/O / N/C)
• Switching delay times

The EDS 4400 is suitable for highpressure applications (starting at 40 bar) and has a pressure measurement cell with thin-film strain gauge on a stainless steel membrane

Special features:

• Option of 1 or 2 switching outputs
• Option of PNP or NPN switching outputs
• High switching output capacity
• Accuracy ≤ ± 1 % FS
• Flexible user-programming
• Compact and robust design
• Also available in ATEX version for potentially explosive locations

General Function:

The programmable electronic pressure switch in the series EDS 4400 has been specially developed to combine the advantages of a compact, robust and cost-effective device with the benefits of a programmable pressure switch

The EDS 4400 can be easily programmed using the HPG 3000 programming unit. Once the programming unit is disconnected from the EDS 4400, the pressure switch retains all the settings. This prevents unauthorised or incorrect adjustment of the settings
