Dual-Frequency Conveyor Metal Detector DD-390 Series
Introduction
The DD-390 Series Dual-Frequency Conveyor Metal Detector is engineered for production lines that require stable, high-precision contaminant detection. Built with advanced digital technology and imported components, it delivers strong anti-interference performance and consistent sensitivity across a wide range of products. The system supports multiple frequencies, intelligent learning, and memory functions to reduce product-effect issues—ideal for high-moisture, high-salt, or oily items.
Its modular design allows easy cleaning and maintenance, while adjustable conveyor speeds (1–1000 m/min) make it suitable for both light and heavy packages. The DD-390 Series can be paired with air blast, pusher, or flapper rejectors and customized conveyor setups, offering a reliable solution for food metal detectors and metal detector conveyor belt applications in modern processing plants.
