1. Product Introduction
Metal detector is a high-precision intelligent testing device based on electromagnetic induction technology, capable of detecting ferromagnetic and non-ferrous metal foreign matters such as iron, stainless steel, copper and aluminum. With adjustable sensitivity, strong compatibility and stable operation, it is widely used in industrial production, public security inspection, geological exploration and other scenarios.
Main product categories cover full-scenario demands: industrial conveyor metal detector for food, mining, chemical and building material assembly lines; security inspection equipment including walk-through metal detectors and handheld detectors for public safety screening; underground exploration metal detector adopting pulse induction technology for archaeological exploration, underwater detection and engineering investigation. Upgraded intelligent models support AI identification, data recording and remote control, adapting to harsh working conditions of high temperature, high humidity and high dust.
2. Working Principle & Core Advantages
2.1 Working Principle
The equipment operates on the electromagnetic induction principle. The transmitting coil generates a stable alternating electromagnetic field during operation. When metal objects enter the magnetic field, eddy current will be induced inside the metal to form a secondary magnetic field, breaking the original magnetic balance. The built-in chip and intelligent algorithm capture and analyze signal changes, accurately identifying the size, position and type of metal foreign matters, and trigger sound-light alarm, material rejection or equipment shutdown in real time.
VLF technology ensures high-precision shallow detection, while PI pulse induction technology resists mineral and environmental interference, realizing deep and large-range detection.
2.2 Core Advantages
High Precision & Wide Coverage: Adjustable sensitivity supports detection of millimeter-level tiny metal impurities and large metal objects, meeting fine and full-range detection requirements.
Strong Anti-interference & High Adaptability: Intelligent filter system shields dust, electromagnetic noise and environmental interference, working stably in various complex working conditions.
High Efficiency & Labor-saving: Fully automatic real-time detection and early warning match high-speed assembly line operation, effectively avoiding manual missed and wrong detection.
Safe & Low Maintenance Cost: Radiation-free, environment-friendly and durable structure with self-diagnosis function, reducing long-term operation and maintenance costs.
Intelligent & Traceable: Supports data statistics, remote debugging and system docking, realizing standardized and visualized production management.
3. Main Application Fields
Food Processing Industry: Applied in full-automatic production lines of meat products, dairy products, snacks and baked food to remove metal impurities, ensure food safety and help enterprises pass international food safety certifications.
Mining & Industrial Manufacturing: Detects metal sundries in ore and raw materials, preventing conveyor belt tearing and mechanical equipment damage, reducing factory shutdown failure and maintenance costs.
