High-precision Visual Displacement Measurement System
Z300
2-Dimensional CCD is Built in. A New Type of
Displacement Sensor Utilizing the Best and Most
Up-to-date Image Processing Technologies.
Features
OMRON's Z300 makes the notion that displacement sensors cannot perform stable measurement of a transparent object
or a glass a thing of the past. The newly-developed 2-dimensional CCD (S-CCD) incorporated in the Z300, combined with
upgraded performance of the controller, provides enhanced stability and accuracy in measurement of a transparent object.
The latest algorithm employed by the Z300 enables optimal sensitivity even if there is a big difference between the amount
of reflected light from the surface and that from the bottom of a glass.
Enhanced measurement area and a variety of high-resolution,
long-distance sensor heads greatly expand the range of
applications.
The Z300 is just another example of OMRON's ongoing
challenge to the limits of sensing possibilities.

B-32 Displacement sensors / Width-measuring Sensors
The innovative 2-dimensional CCD (S-CCD) is the key to the sensing performance.
A conventional displacement sensor using a 1-dimensional
CCD cannot deal with flutter influence to the output. There-
fore, the sensor requires increased number of measurements
for signal averaging, which leads to slow response time. The
S-CCD with a 2-dimensional CCD has solved this disadvan-
tage, by splitting the measurement point into 60 lines for mea-
surement in finer detail. The value per each pixel is then
averaged to produce a reliable output, free from flutter influ-
ence caused by the object's surface condition. Stable detec-
tion and high-speed processing is thus possible with the Z300.
The 2-dimensional CCD enables stable, high-speed
measurement.
CCD makes a difference in measurement of a
transparent object.
PSD sensor
A PSD sensor using dif-
fuse reflection is virtually
prevented from perform-
ing measurement due to
insufficient reflection dis-
tribution from the surface.
A sensor using the mirror
reflection method, on the
other hand, receives re-
flective light from the bot-
tom or background of the
object, which causes an
error in determining the
target position, impeding
accurate measurement.
CCD sensor
A CCD using the mirror re-
flection method is a solu-
tion. It can extract only the
light reflected off the sur-
face of the target. Accu-
rate measurement of a
transparent object is pos-
sible without being affect-
ed by reflected light from
the bottom or background
of the object.

Monitoring as the object is being measured.
Measurement data can be recorded and played back.
Easy-to-see color display is another great feature of the Z300 (when connected to a color monitor). Monitoring at each key stage
including test and adjustment, operation, or maintenance greatly facilitates efficient, error-free measurement.
Real-time monitoring
Digital monitor Image monitor Trend monitor
The measured value is displayed. The use of two
colors: green for "Pass" judgement, and red for
"High/Low," enhances visual recognition of the
measurement result.
Displays the position of measurement point as well as
intensity of the reflected light.
Conveniently checks whether optimum measurement
is taking place.
Continuous measurement values during a certain
period of time are shown in chronological order.
Changes in the measured values of a moving or
rotating object can be checked at a glance.
Monitoring during recording and playback
Test mode Conditions during Test mode can be
recorded and played back
NG (High/Low) judgement status is
recorded and played back.
Any desired number of measurement data can be
stored for testing with a workpiece. Test measurement data obtained off-line can be saved for reference for actual in-line measurement. Up to 20 in-line NG data (information including reflected light condition and measurement data) can
be recorded for workpiece analysis as well as for
troubleshooting.
