Highly Accurate Sensors Can Also Be Adaptive

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

Roll-2-Roll Technologies' WPS 440 is a versatile sensor with an integrated sensor control unit, a 440 mm sensing window, and multiple functionality. The sensor technology requires no setup or calibration. The sensing principle relies on light scattering and spatial filtering properties of fiber optics to accurately determine the features on the web. The 440 mm sensor version is suited for edge guiding applications with frequent width changes, web width measurement, center guiding, etc. The sensor is also used in simple inspection applications such as thread counting, string coverage, void detection, etc.

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.
