920089 EDS 4448-0040-1-PP-000 HYDAC PRESSURE SWITCH

920089 EDS 4448-0040-1-PP-000 HYDAC PRESSURE SWITCH
The programmable electronic pressure switch in the series EDS 4400 was specially developed to combine the advantages of a compact, robust and costeffective instrument with the benefits of a programmable pressure switch.

FEATURES

• 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.
• The following parameters can be changed: Switch point, Hysteresis, Switching direction (N/O / N/C) and 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.
• An ATEX version of the EDS 4400 is also available for use in potentially explosive atmospheres.
