## Transcript

Hello, this is Pedro Velasco with Roll-2-Roll Technologies. Today we're going to talk a little bit about one of our sensors in our web positioning sensor line. So imagine this, what if you have a line where you're trying to run several strands like wires and material so you want to monitor if the wires are there or not. In this case the WPS 440 can actually give you that application.

In this case, I have set up right now seven wires that in the production line probably running over the face, separate from the face that would be running across it right. So if I eliminate, even one take it away, you would actually get a signal telling you that it has been removed, it's missing and that would be one of the features of this product one of the applications. At the same time, if these wires come together then it also can tell you that that is happening also tell you that there's a problem in the system. Additionally it can actually give you just measure each one of the wires and give you an average of the measurement of the width of each wire and then at this same time tell you there's a problem with your system so this is one of the features of the WPS 440- 440 millimeter sensor window and included with the SE unit and closed within the housing unit.

It's all available to you through our Roll-2-Roll Technologies. You can see more information about the sensor at www.r2r-tech.com
