Z300

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.
