Kronz Ultrasonic  single -and -double -sheet Sensors

    Kronz ultrasonic single -and -double -sheet detection sensors are primarily used to detect whether sheets of paper, plastic, or metal film are single or unintentionally stuck together as multiple layers. The sensor continuously compares the detected values with stored reference values and outputs signals indicating single or multiple layers, unaffected by the color of the material.

Working Principle

    An ultrasonic transmitter emits a high-frequency ultrasonic beam from below the sheets. The sound wave causes the sheet to vibrate, generating a very small sound wave on the other side of the sheet, which is received by the ultrasonic receiver. When the signal passes through two sheets (double sheet), it becomes very weak and cannot reach the receiver.

Product Features

• Durable and Multi-protected, ensures long-lasting performance with multiple protective features.
• Strong Anti-interference,high sensitivity, fast response, and strong stability.
• Unaffected by Material Attributes: Works regardless of the material's surface, color, or size.
• Adapts to Harsh Environments: Functions in dusty, dirty, foggy, and light-rich conditions.
• Transparent and Bright Object Detection: Capable of scanning transparent and shiny objects.
• Detection Distance: Ranges from 20mm to 60mm or 20mm to 100mm.
• Material Thickness Range: Can detect materials with thicknesses ranging from 0.01mm to 3mm.

Industry Applications

    Single -and -double -sheet sensors are widely used in various industries, such as printing machines, assembly machines, folding machines, packaging machinery, solar cell and silicon wafer manufacturing, labeling, and PCB manufacturing.

Examples:

• Printing Machines: Identifying double sheets during paper transport.
• 
• Stacking Machines: Differentiating between single and double lithium electrode sheets during grabbing.
• 
• Laminating Machines: Detecting sheet overlap and double sheets.
