Tunnel type metal detector GMD-T

for conveyorwith separatorhigh-precision

GMD-T Metal Detector is a conveyor-integrated tunnel metal detector engineered for high-precision inspection of moving products. It features a multi-frequency detection system to identify ferrous, non-ferrous and stainless-steel contaminants while supporting full production-line integration and traceability.

Key features

• Multi-frequency detection: detects ferrous, non-ferrous and stainless-steel metals with automatic sensitivity adjustment per product.
• Integrated conveyor: modular, adjustable transport system that adapts to various product sizes and formats for stable inspection.
• Automatic rejection system: configurable pneumatic piston, air blast (single or dual) or rejection paddle to remove contaminated items without stopping the line.
• Compliance and traceability: designed for IFS/BRC requirements with built-in calibration, data logging and HACCP reporting options.
