The document describes the Ultrasound edge sensor FX 5030, FX 5060, and FX 5100, which are specially designed ultrasound sensors for detecting the edges of materials such as paper, foil, or film that are impermeable to sound. The sensor ensures reliable web edge detection even on foils with a high and dramatically fluctuating degree of transparency. The integrated LED strip in the receiver helps the user to manually position the sensor. The display can be switched off when used with light-sensitive materials. The wide measuring range eliminates the need for motor-driven sensor follow-up when the width fluctuates only minimally. A width measuring function is generally included in conjunction with motor-driven support beams and web center guiding.
