Application Case | Troubled by Detection of High-Reflective Thin Sheets? Here’s Your Solution~
Release time:2026-07-07
Application Case: Presence Detection of Silver Aluminum Burst Disc (1–2 mm Thick) on Production Line
- Mounting position: The sensor is installed atop the equipment, emitting laser vertically downward.
- Detection distance: The burst disc sits 120 mm vertically below the sensor.
- Optical path constraint: The laser beam must pass through a tiny hole with a diameter of only 5 mm to reach the target.
- Target characteristics: The aluminum burst disc features an ultra-smooth, mirror-like reflective surface.
Solution
Solution Advantages
Ultra-small light spot design for seamless passage through the 5 mm aperture
The LC-S Series features a laser beam spot as tiny as Φ50 μm, far smaller than the 5 mm mounting hole. Even when the optical path runs through narrow channels, the complete light spot can fully project onto the target without any obstruction from the hole edge.
High-precision measurement capability
Multiple precision grades are available for Heyi laser displacement sensors, with repeatability up to 10 μm — vastly exceeding the 1–2 mm measurement requirement for this application.
Laser triangulation principle to counteract high reflectance interference
Adopting the laser triangulation measurement principle, the sensor effectively suppresses reflective noise generated by the aluminum disc surface and surrounding stainless steel components, enabling consistent and dependable detection results.
Versatile output options for seamless integration with control systems
Equipped with single digital switch output, combined digital switch + analog output, and RS485 communication output, alongside multiple built-in detection modes. The diversified functions support a broad range of industrial application scenarios.
Extended Application Scenarios
- Thickness/height sorting and discrimination of precision components: Position detection and part identification for molds and hardware fittings.
- Residual material monitoring for large coiled materials: Precise measurement of coil diameter and film residual volume on winding machines during new energy battery manufacturing.
- Flatness inspection for flat glass and silicon wafers.
