ARIS Web Position Sensor can automatically detect any material without the need for calibration. This video shows the sensor capabilities, such as accuracy, precision, linearity, with four materials.

## Transcript

Our web guiding system, ARIS, features the latest in web guiding technology. It adapts to any material, requires no calibration, and is very simple to set-up. Our technology allows the sensor to be material agnostic, which means ARIS accurately detects the web edge position of any materials used without the need for manual adjustments. ARIS’ sensor technology works differently than any other currently available sensor in the market.

It uses the reflection of infrared light to take a picture of the edge of the material. This picture is then processed using digital signal processing algorithms to accurately sense the true position of the material irrespective of its physical properties. Other sensors use a blocking technique where the web is used to block light, sound or air. Since the amount of blocking depends on the material properties, the current sensor technology is less accurate with porous or transparent material.

Ultimately the web guiding performance is affected by the inaccurate sensor measurement. In this experiment, we will show you four materials, black nonwoven material, white nonwoven material, transparent film, and burlap. Our experimental setup is equipped with a high precision motor stage which moves the web material, which is 10 mm away from the sensor, back and forth. This setup is used to quantify the sensor performance.

With each material we repeat the exercise four times. The green line represents linear regression, which quantifies the precision and accuracy of the sensor. The blue represents the actual position of the web as measured by the sensor. Follow the results as the experiment progresses.

The video shows the web as it moves away from the center and the sensor’s ability to follow the position. The experiential results clearly show that the precision and accuracy of the sensor is unaffected by the material properties. Our sensor has linearity of plus or minus 1 percent without any calibration. Find out more information about ARIS and our sensors, using the link in our description below.
