Ultrasonic application: web guiding controlGeschrieben am 1. Mai 2010 Keine Kommentare
The UPF-A are ultrasonic through beam sensors with separated transmitter and receiver. They are suited for edge detection on web guiding systems. In contrast to conventional barriers they do not offer a simple on/off output signal, but they measure the degree of covering of the ultrasonic receiver as an analogue output signal. If the receiver is fully covered, the output is 0V and if not covered at all 10V or vice versa.
With their large measuring range they are the perfect tool for web guiding applications in dusty environment and with transparent web material. These sensors can be used in packaging industry for web guiding control. Very typical material for ultrasonic web guidance control are transparent or partly transparent plastic wrap foils because they cannot be reasonably detected by optical sensors.
But many other applications are open to this product, such as edge detection for many materials.
