Ultrasonic Dual Detector Ultrasonic Proximity Switch Double tension Detection Sensor

Discription

The double-sheet detection system is designed for a special application of the radiation sensor. This application was originally designed for the printing industry. Ultrasonic through-beam sensors are used to detect the thickness of paper or sheet.

The ultrasonic double sheet detector is suitable for identifying:

• Paperless, single or double sheet
• Base material
• Labeled base material

The ultrasonic double-sheet detector is used to automatically and high-speed discriminate substrate materials, labels, single sheets and double sheets, thereby protecting the machine from waste in the production process. The entire system includes an ultrasound transmitter, an ultrasound receiver and a processor external or built into the receiver. These components are already configured at the factory and cannot be used separately.

Feature

• Detectable range from 30g / m2 paper to 2000 g / m2 cardboard
• Can also detect plastic or metal foil
• Can be set for different materials
• Suitable for smooth or transparent materials
• Automatic compensation when the environment changes slowly
• High processing speed
• Insensitive to dirt and dust

Typical Applications

• Used in printing presses, ultrasonic double sheet detection prevents inadvertent conveyance of two sheets of paper, so as to damage the precision mechanical mechanism, or to ensure that the second sheet is not in the machine
• Check whether the label is attached to the substrate and the number of labels applied by the labeling machine
• Apply to letter openers to make sure the open envelopes are completely empty
• Ultrasonic double-sheet detection on billing machines to determine if bank bills are being counted correctly
• Used in packaging machinery to detect the junction of two sheets of paper to adjust the progress of the machine
• For paper processing machinery, detecting paperless, single-sheet and double-sheet
