ARIS WPS 221-IR offers a 221 mm sensing window, with a sensor resolution of 0.125 mm, offering all the benefits of the smart sensor technology for the detection of any material without the need for calibration.


Reliable web guiding in any setting with a wider sensing window

Detecting and guiding the material efficiently requires accuracy and that is what ARIS Web Position Sensor guarantees. Changes in environmental settings are no problem with our technology. All our sensors are unaffected by ambient light, temperature, and sound vibrations, making them reliable in any setting.

Edge detection and monitoring, width monitoring or measurement, center guiding, string position detection and monitoring, multiple string detection, multiple string counting, and moving stack measurement and monitoring. These capabilities allow for multiple applications not only in web guiding, but also in web monitoring and inspection.
