Electronic Pressure Switch Launched

AFRISO’s new EDS 10 electronic pressure switch converts the pressure of liquid or gaseous media into an electrical signal. EDS 10 allows the user to define up to two selectable points for switching  or switching back. The unit is programmed by means of two keys and the menu. The pressure switch can be rotated by 330° and tilted by 300° so that it can be used under adverse mounting conditions. A 4-digit 7-segment LED display shows the system pressure (selectable pressure units bar, mbar, psi or MPa).

The pressure switch features a piezo-resistive stainless steel measuring cell. Sensors are available for all standard measuring ranges from 0/100 mbar to 0/600 bar. Starting at a nominal pressure of greater than 1 bar, EDS 10 is vacuum-tight without limitations. At 0/400 mbar and higher, the accuracy amounts to ≤ ±0.35 %.

The EDS 10 is supplied with DC 18–30 V and provides, depending on the requirements, two PNP or NPN switching outputs, alternatively a 4 –20 mA output plus PNP or NPN output (all in SIO mode). EDS 10 was developed for 100 x 108 switching cycles with a switching frequency of up 200 Hz and delay times from 0 to 50 s.

The new measuring instrument is suitable for temperatures of the medium of -40/125 °C. All standard ¼" or ½" connections are available for the process connection. A 4-pin M12 x 1 metal connector is used for standard electrical connection. The pressure switch is optionally available with other seal materials (EPDM) and other electrical connections. Main application areas comprise monitoring of gaseous or liquid media in plant engineering and mechanical engineering. EDS 10 is an ideal solution for hydraulic and pneumatic systems where high switching accuracy is required.
