The Ultrasonic Double Material Detection Technology Guide from Pepperl+Fuchs is a compendium that comprises much of the content of the “Technology Guide Ultrasonic Sensors” with a special focus on double material detection. Double material detection symbolizes the common detection process in which ultrasonic sensors measure the material-related attenuation between the emitter and the receiver.
It covers typical applications such as double sheet detection in the printing industry. Thus, sensors are used to check whether one or more sheets are fed into a printer. Moreover, the compendium also contains explanations of other applications such as ultrasonic splice detection or label inspection and helps find the factors that influence measurement accuracy in double material detection.
