Pressure Switch
EDS 601
The EDS 601 is an electronic
two-channel pressure switch with
display and analogue output.
Its digitally adjustable switching points
and switching hystereses make it
particularly suitable for applications
requiring frequent change-overs or
accurate switch point setting.
The variety of setting parameters
ensures versatility for use in all control
and monitoring tasks in hydraulics,
pneumatics, process control and in
general test and control engineering
applications.
Special features:
