Even in the harshest
environments,
the WideArray edge detector gives you
more consistency,
accuracy and reliability.
|
|
Accuweb's dynamically compensation array edge detectors offer a
wide
sensing range ̶ using either ultrasonic
or infrared sensing technology.
|
WideArray™ Edge Detectors
feature large detection ranges to accommodate variations in web width.
Web widths can be changed on the fly, eliminating the need to physically
reposition edge detectors. Rugged and compact in size, a WideArray is
easily mounted and requires only a single cable. Every WideArray
features AccuWeb’s patented Compensated Array Technology that
automatically compensates for dust, changes in temperature and humidity,
as well as web flutter and passline variances, along with other
environmental factors.
|
|
|
|
Compatible with
Micro 1000®
and
Micro 4000® NET controllers |
 |
• Dynamically Compensated — Our exclusive technology automatically adjusts for all
environmental, process and web changes — temperature, relative humidity,
barometric pressure, dirt, dust, Oxi-Dry, nitrogen additions, web
flutter, or passline variations. |
|
Handles up to
36.8" (935 mm)
variation in
web width |
 |
• Any Web Material — AccuWeb’s compensated edge detectors are available in
ultrasonic and infrared technology to effectively guide all web
materials — paper, film, foil, nonwovens, mesh, metals — regardless of
opacity level or density. Select either ultrasonic or infrared models
depending on materials. |
|
Available in ultrasonic
or
infrared models |
 |
• Totally Automated – No Maintenance — Our compensated edge detectors
self-calibrate automatically. No operator adjustments necessary –
resulting in faster make-ready. Other than an occasional wipe down, no
maintenance is required. |
|
Adjustable guide point
via
remote station
or
PLC Interface |
 |
• Hazardous Duty Operation — Intrinsically safe models are available to operate
in Class I, Division 1 Group C&D hazardous environments. |

• The WideArray is ideal for any application
that requires an increased detection range. Applications include edge
guiding, centerline guiding, electronic oscillation to reduce guage-band
build-up, positioning one web relative to another, measuring web width, and
monitoring edge or centerline position.
• A remote station can be located anywhere, allowing operators to easily
adjust guide points in .001 inch increments within the wide detection range.
Now operators can fine-tune web position with digital accuracy and
repeatability.
• The WideArray is ideally suited for chaser/slave applications typically
found in laminating, thereby replacing complicated
and high-maintenance mechanical positioning devices.
• Web guage position and guide point can be communicated via PLC inputs using
the Micro 4000®NET Controller.

The advantage of patented dynamically compensated array edge detection
technology
Multiple pairs of emitters and receivers create the seamless
detection area of the WideArray. Four beams are active at all times,
three for locating the edge of the web, the other to monitor the
environment adjacent to the web.
As the web edge moves within the WideArray detection range, the
compensation point moves with the web edge, constantly adjusting for
changing conditions. |
|
|
WideArray edge detectors feature a wide range that can automatically
detect webs of differing widths, speeding changeovers. WideArrays are
available in both ultrasonic and infrared configurations to accurately
handle any web material. |
