Electronic Pressure Switch EDS 4400 Programmable
Description:The programmable electronic pressure switch in the EDS 4400 series has been specially developed bine the advantages of pact, robust and cost-effective instrument 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 adjustment of the settings.
The following parameters can be changed:
???Switching point
???Hysteresis
???Switching direction (N/O / N/C)
???Switching delay times
The EDS 4400 is suitable for high pressure applications (over 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 permanently pre-set according to customer requirements, the programmable EDS 4400 is highly versatile and replaces a wide range of models. This is advantageous in respect of stock management. Special features:???Option of 1 or 2 switching
outputs???Option of PNP or NPN switching outputs???High switching output capacity???Accuracy ≤± 1 % FS ???Individual programming? Compact and robust design???Also available in ATEX version for potentially explosive locations
Technical Data:Overload pressures 80; 200;
