Highly Accurate Sensors Can Also Be Adaptive

Eliminate calibration. These sensors learn and adapt on the fly!

Web Position Sensors can measure edge position of any material without the need for any setup or calibration. The sensing principle relies on light scattering and spatial filtering properties of fiber optics to accurately determine the web position. The 112 mm sensor version is a versatile sensor in the Roll-2-Roll Sensor family that can be used for edge sensing/guiding, contrast position sensing/guiding, line guiding, mark detection, and more. The wider sensing window provided by WPS 112 allows for 4" of web width change capacity in single edge guiding applications or up to 8" width change capacity in center guiding mode without the need to re-position the sensor. The sensor head along with the sensor control unit forms the complete sensing solution.

The patented fiber optic sensing principle enables the plug-and-play sensor technology. The sensor technology adjusts automatically to the physical characteristics of the material and provides an accurate position measurement. The WPS 112 is essentially an affordable vision based sensing system different web sensing applications.
