Metal Detector

Applications & Use Cases

• Used for detecting metallic contaminants in food products, ensuring product safety and compliance.
• Applied in pharmaceutical manufacturing to identify metal particles in tablets, capsules, and powders.
• Integrated into packaging lines to inspect finished goods for unwanted metal inclusions.
• Utilised in textile production to detect broken needles or other metal fragments in fabrics.
• Employed in plastics and recycling industries to remove metal from raw materials, protecting downstream machinery.

Typical Specifications

Typical aperture size

Varies significantly, but commonly ranges from 100mm to 500mm in width and 50mm to 300mm in height for this class of equipment.

Power supply

Typically requires a single-phase or three-phase electrical supply, commonly 230V or 400V, 50Hz, for units of this type.

Detection sensitivity

For this class of equipment, sensitivity is typically in the range of 0.5mm to 3.0mm for ferrous, non-ferrous, and stainless steel contaminants, depending on product effect.

Conveyor speed

Commonly adjustable, with typical speeds ranging from 10 to 60 metres per minute, depending on the application and product size.

Construction material

Often constructed from stainless steel (e.g., 304 or 316) for hygiene and durability, particularly in food and pharmaceutical applications.

Environmental protection

Many units feature an IP rating, typically IP65 or higher, indicating protection against dust and water ingress.
