GMD-T Metal Detector with Conveyor Belt and Multifrequency Inspection
The GMD-T is a metal detector with an integrated conveyor belt, designed for maximum accuracy inspection of moving products. Its advanced, multi-frequency detection system guarantees the identification of ferrous, non-ferrous, and stainless steel metals, complying with the strictest quality and safety regulations. This equipment is the ideal solution for enhancing product safety and manufacturing process efficiency.
Key Features and Advantages
The GMD-T is a sophisticated inspection solution featuring the following key functions:
Multifrequency Detection
The system is capable of detecting ferrous, non-ferrous, and stainless steel metals in moving products with exceptional accuracy. The detection sensitivity automatically adjusts to the type of product being inspected, thereby optimizing performance and minimizing false rejects.
Integrated Conveyor System
Modular, adjustable conveying system that can be easily adapted to different product sizes and types. This ensures a continuous and stable inspection process, preventing product jamming or damage.
Automatic Rejection System
Contaminated products are safely removed from the production line automatically. The system supports multiple rejection methods (pneumatic piston, air blast, or rejection flap), ensuring maximum efficiency without production downtime.
Compliance and Traceability
The GMD-T is designed to comply with the strictest industry standards, such as IFS/BRC requirements. It features built-in calibration and data logging protocols that support audits and quality control processes, ensuring full traceability.
