Electronic Inspection and Metal Detection

Gravity Metal Detectors

MPI Gravity Metal Detectors are engineered for fast, efficient detection and removal of ferrous and non-ferrous contaminants from free-falling granular or powdered products. Ideal for food, plastic, pharmaceutical, and chemical industries, these systems use high-sensitivity sensors and fast-reacting reject mechanisms to maintain product purity without slowing throughput. Gravity Metal Detectors protect products from metal contaminants in gravity-fed processing lines. Products include the compact Gravity Feed Metal Detector, the Gravity Feed Metal Detector PH (Pharma), the Metal Detector R (Ring Sensor), the Pro-Tector, and the Throat Metal Detector.

Belt Metal Detectors

Designed to integrate seamlessly into conveyor systems, MPI Belt Metal Detectors offer continuous monitoring of both bulk and packaged products. These detectors identify metallic contamination as products move along the line, automatically triggering alarms or rejection systems to prevent contaminated material from progressing further. Their rugged design and customizable aperture sizes make them suitable for a wide variety of processing environments. Belt metal detectors protect products on belt-conveyed processing lines. Products include the BIG Detector, the C0680 Large Bag Detector, the Packaged Goods (BD) Detector, and the Tunnel (TU) Detector.

Metal Detector Controllers

MPI’s advanced Metal Detector Controllers provide intuitive operation, real-time system diagnostics, and precise adjustment capabilities. These controllers enhance detector performance with features like sensitivity tuning, reject timing, and data logging. Their user-friendly interfaces support quick setup and integration into existing control systems, enabling optimal line efficiency and traceability. Manage your metal detector sensitivity and reporting with metal detector controllers including Metal Shark 2 Controller and Sharknet Software Controller.

X-Ray Inspection and Checkweighers

MPI’s X-ray inspection systems go beyond metal detection, offering comprehensive contaminant identification—including glass, stone, bone, and dense plastic—while also verifying product shape, count, and fill levels. Paired with precision checkweighers, these systems ensure both quality control and compliance by verifying package weight and detecting anomalies, making them essential for food, pharmaceutical, and consumer goods applications. Ensure finished products meet quality standards with electronic inspection tools, including Checkweighers and X-ray inspection for Bulk Products, Glass, Jas, and Can Lines, Liquids, and Packaged Goods.
