GJT-F Precision Metal Detector

The GJT-F Industrial Conveyor Metal Detector is an advanced metal detection system specifically designed for continuous production lines and conveyor belt applications. Equipped with a modular differential transformer sensor and advanced digital phase-shift detection technology, the detector delivers exceptional sensitivity, reliable performance, and superior resistance to environmental interference.

The system is widely used in industries such as power generation, cement manufacturing, building materials, paper production, mining, food processing, and chemical manufacturing. It effectively detects ferrous and non-ferrous metal contaminants mixed within bulk materials, helping protect downstream equipment from damage while maintaining product quality and production safety.

When metal passes through the detection area, the sensor generates an electromagnetic induction signal. The signal is amplified and processed through a high-performance control circuit, which then activates the alarm system or connected equipment. The detector can be integrated with conveyor systems, reject mechanisms, and production automation equipment for continuous monitoring and automatic contamination control.
