Ultrasonic Double Sheet Detector

Ultrasonic double sheet detection detects the difference between no sheet (air), single sheet, and double sheets. The standard 18 mm diameter unit detects paper, thin plastics, and foils with weights from 10 g/m2 to 2000 g/m2. The sensor is equipped with four evaluation programs to detect a variety of materials. No TEACH-IN is required, and an output pulse extension of 120 ms is possible. The 30 mm ultrasonic double sheet detectors offer the same features as the standard version while providing a larger (50 mm - 150 mm) separation range and the ability to detect thicker materials. The UDCM-30GM-085 metal sheet detection sensor ensures that only one metal sheet feeds to the press by detecting the difference between a single or double sheet of metal.
