Products Background Image
Request Information
The programmable electronic pressure switch in the series EDS 4400 was specially developed to combine the advantages of a compact, robust and cost-effective instrument with the benefits of a programmable pressure switch.

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

The following parameters can be changed:
  • Switch point
  • Hysteresis
  • Switching direction (N/O / N/C)
  • Switching delay times
The EDS 4400 is suitable for high-pressure applications (starting at 40 bar) and has a pressure measurement cell with thin-film strain gauge on a stainless steel membrane.

In contrast to pressure switches which are factory-set acc. to customer requirements and not field-adjustable, the programmable EDS 4400 is highly versatile and replaces a wide range of models. This is advantageous in respect of stock management.

An ATEX version of the EDS 4400 is also available for use in potentially explosive atmospheres.
