Description:
EDS 8000 is an electronic pressure switch
in compact design which is simple to adjust.
Models with one or two transistor outputs (PNP
or NPN) are available.
The switch points are set using the two keys
and a four-digit display. During operation the
switching position is indicated by either a red
or a green backlight in the display.
For optimum adaptation to a particular
application, the instrument has many
additional adjustment parameters, e.g.
switching delay times, N/O / N/C function of
the outputs.
EDS 8000 is available in various pressure
ranges between 0 .. 25 bar and 0 .. 600 bar.
The main applications of the EDS 8000 are
to indicate pressures and limits in hydraulics
and pneumatics, or any application where
high switching frequency or constant
switching accuracy would overburden a
mechanical pressure switch.
