Conveyor Belt Metal Detector Overview

The SameGram conveyor metal detector is designed for inline inspection on conveyorized production lines. They can detect ferrous (Fe), non-ferrous metals, and stainless steel (SUS) contaminants in products such as bulk food, bags, bottles, pharmaceutical tablets, and cosmetic packaging. Typical industries include bakery, snacks, dairy, meat & poultry, seafood, pharmaceuticals and chemicals.

Built-in multi-frequency signal processing module
Auto-adjusts frequency based on product properties
Differentiates metals from actual product content
Reduces false alarms during high-speed operation
IP65-rated for water and dust protection
Stable under electromagnetic and temperature changes

Foil Packaging Detection

Accurately detects contaminants even in aluminum-foil-sealed products — a common blind spot in traditional metal detectors.

Multi‑Frequency Technology

Auto or manual multiple frequency selection reduces product effect and improves detection across different product types and packaging.

SameGram Metal Detector Touchscreen Operation

High Sensitivity

Detects small metallic fragments (down to 0.8–1.5 mm depending on product & aperture) — sensitivity table in specifications.

SameGram Metal Detector Modular Integration Ready

Integration & Connectivity

Standard I/O, RS‑232/RS‑485, Ethernet, and optional OPC/Profinet for MES/ERP integration. Compatible with rejectors and checkweigher systems.

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.
