E-DAP-2
Compact electronic pressure switch with
integral digital display, available for 3 dif-
ferent pressure ranges.
The working pressure is real time measured
and monitored on a 4 digits display
in
bar, Mpa, kPa, psi or kg/cm². The display
can be mechanically rotated on 1 axis
and turned electronically through 180°.
It provides two independent output with
electronic contacts which are triggered
when the pressure in the hydraulic circuit
reaches the switch point or window (see
section
).
The functional parameters as the pressure
switching point, hysteresis range, pressu-
re measuring units and others additional
functions can be easily set by the end
user trough proper programming keys
.
For detailed instructions about the use of
the electronic pressure switch refer to the
operating manual supplied with the instru-
ment.
Features:
• Standard 5 pin M12 main connector
• IP65 / IP67 protection degree
• CE mark according to EMC directive
