Ultrasonic label sensor esp-4 series

esp-4: Label and splice sensor compact in a single unit, optionally with M12 sensor heads. Highlights 3 Teach-in methods to be able to configure the sensor individually for any task Response time < 300 µs for use at high web and label speeds QuickTeach simplified Teach-in process Splice detection even for thick band materials Variants with very compact transmitters and receivers in the M12 threaded sleeve Basics Label and splice sensor in a single unit 2 switching outputs for label/splice detection and web break monitoring LinkControl as optional assistance for installation and commissioning Description With a rapid pulse sequence, an ultrasonic transmitter beams upwards against the backing material. The effect of the sound pulses inducing the backing material to vibrate is for a markedly weakened sonic wave to be emitted on the opposite side. The receiver receives this sonic wave and analyses it. The backing material signal level is different to that of the label or splice. And this difference in signal is analysed by the esp-4. The difference between backing material and a label or between sheeting and splice can be very slight indeed. In order to differentiate, the esp-4 sensor has to learn the signal level for the backing material or sheeting. The esp-4 sensors can be used as a label and splice sensor. The 3 Teach-in methods and QuickTeach allow the esp-4 sensor to be optimally set for each and every assignment. A) Dynamic Teach-in of backing material and label During Teach-in, the backing material with the labels is led at a constant speed through the esp-4 sensor. The esp-4 sensor automatically learns signal levels for the labels and for the gaps between them
