    3 Weeks Lead Time
Highly Accurate Sensors Can Also Be Adaptive

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

Roll-2-Roll 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 221 mm sensor version is suitable for a variety of applications requiring wide sensing range. Most typical application include edge sensing/guiding, width measurement, center guiding, guiding with dynamic guide point adjustments, etc. 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. WPS is essentially an affordable vision based sensing system different web sensing applications.
