Industrial Metal Detector for Reliable Inline Contaminant Control

Foil-CompatibleMoisture-ProofAuto-Calibrating

Samegram metal detectors utilize advanced multi-frequency signal processing to detect ferrous, non-ferrous, and stainless steel contaminants with high sensitivity. Designed for food, dairy, pharmaceutical, and chemical industries, they ensure zero metal contamination in automated production lines. We offer both free fall metal detectors for bulk powders and granules, and conveyor metal detector systems for packaged goods. Our detectors help meet global standards such as ISO and HACCP. For enhanced efficiency, we also provide combination metal detection and checkweigher systems, enabling integrated quality control. These metal detector checkweigher units ensure precise weight compliance and contaminant detection in one compact solution.

Related Cases

A major food processor in East China specializing in packaged baked goods such as bread and biscuits upgraded its quality control with Samegram’s advanced metal detection system. Facing high false alarms and blind spots due to aluminum packaging and oily environments, the company needed a precise and export-compliant solution. Samegram deployed a dual-frequency detector with interference suppression algorithms and a high-speed pneumatic rejector. This reduced false alarms by 85%, improved detection accuracy to 99.8%, and increased output by 18%. The system meets HACCP and ISO22000 standards, enabling smoother exports to Japan, Southeast Asia, and the Middle East.
