Device
Overview
The
DME
2000
is
a compact optical
dis
-
tance sensor. lt measures the
light
transit-
time according
to
the p
ri
nc
ipl
e
of
ph
ase
correlation. T wo
diffe
rent operating
modes are
available:
scanning
mode for
measurement
of
almost a
ll
surfaces,
and
refiector mode for great distances em-
ploying
refiective
foil.
T
yp

includ
e the positioning
of
