High Performance Textile, Foil, and Fleece Metal Detection
Flat (FL) sensor for installation below or above conveyed material to provide the highest performance in detecting magnetic and non-magnetic metals. Typically, the FL types are used in fleece, textile and foil production.
The METAL SHARK® FL is a flat metal detector designed for installation under or between conveyor lines, specifically for inspecting non-wovens, textiles, fabrics, and films. Its flat detector surface, combined with rotatable mounting hardware, allows alignment with ascending or descending product paths, facilitating easy integration into existing conveyor systems.
Utilizing CASSEL's proprietary 4-quadrant technology, the METAL SHARK® FL achieves high detection sensitivity, capable of identifying even tiny magnetic and non-magnetic metal particles, such as iron, aluminum, and stainless steel, across the entire width of the product. The system features autocalibration and a TeachAssistant for intuitive control and straightforward installation. Additionally, it offers low maintenance with automatic balance and calibration control, ensuring reliable operation over time.
Benefits of the Flat Plate Metal Detector From Magnetic Products, Inc
-
Ultra-Low Profile for Flexible Mounting
The flat design enables seamless installation under or over conveyor lines, making it ideal for existing systems with limited vertical space.
-
Full-Width Surface Detection
Monitors the entire product width for metallic contaminants without requiring product encapsulation—ideal for sheets, films, or mats.
-
High Sensitivity to All Metal Types
Accurately detects ferrous, non-ferrous (e.g., aluminum, brass), and stainless-steel contaminants, including small particles or fine wires.
-
Versatile Integration Options
Installs easily in a wide variety of continuous process environments, from clean production floors to rugged industrial conveyors.
-
Fast Detection with Minimal Delay
Real-time signal processing ensures immediate contaminant detection—allowing reject systems or alerts to activate instantly.
-
Non-Intrusive Design
The flat plate sensor doesn't interfere with product flow, belt alignment, or surface contact—maintaining production continuity.
-
Durable, Industrial-Grade Construction
Built for reliability in continuous operation environments with vibration resistance and corrosion-protected housing.
-
SharkNet® Ready for Centralized QA
Compatible with MPI’s SharkNet® software for live monitoring, event logging, and compliance with 21 CFR Part 11 documentation standards.
Flat Plate Metal Detector Product Details
MPI’s Flat Plate Metal Detector operates using an inductive sensing plate that is installed either directly below or above a conveyor belt. As product passes across the sensor plate, an electromagnetic field is generated and continuously monitored for disturbances.
When a metallic contaminant passes through or over the sensing area, it creates a disruption in the field. The system’s digital signal processor analyzes this signal, determines if it exceeds preset thresholds, and immediately triggers an alert or activates a reject mechanism downstream.
The sensor plate provides uniform sensitivity across its entire surface area, ensuring that contaminants are detected regardless of their lateral position on the product. It’s ideal for applications where the product cannot pass through a tunnel or where space prevents the use of larger detection systems.
