Double sheet sensors are used to monitor layers of materials as they are fed into machines. While the default settings for Pepperl+Fuchs’ double sheet sensors are suitable for over 90% of all usable materials, it is important to consider the following factors before choosing which settings to use: environmental conditions, material characteristics, and alignment accuracy. Each of these can affect measurement accuracy in double sheet detection and must be accounted for.
Ultrasonic double sheet sensors help ensure continuous, error-free processes in a range of industrial applications. They are used to prevent more than one layer of material from being fed into a machine. The same technology behind double sheet detection can also be applied to label detection applications.
