Tunnel Metal Detector Machine for Industrial

Product Description

Product Introduction

The MDH-4012 Industrial Metal Detector

The MDH-4012 Tunnel Metal Detector is a robust, high-performance detection system specifically designed for heavy industrial applications. Unlike standard detectors, this unit is built to withstand the harsh realities of mining, quarrying, and cement production. It features advanced digital signal processing that intelligently filters out background noise from iron oxides and ores, ensuring accurate detection of dangerous metal contaminants like excavator teeth, drill bits, and scrap metal.

Whether protecting your crushers from catastrophic damage or ensuring purity in recycling lines, the MDH-4012 delivers unmatched reliability. Its solid-state construction resists vibration, dust, and impact, making it the ultimate guardian for your production line's safety and efficiency.

Advanced Functions

Why Choose the MDH-4012?

• Intelligent Ore Immunity Technology:
  Eliminates false alarms caused by mineralized ground. The advanced DSP algorithm distinguishes between valuable ore/iron oxide and harmful tramp metal, ensuring your line keeps running without constant stoppages.
• Ruggedized Vibration Resistance:
  Built to survive where others fail. The probe and amplifier are solidly constructed to withstand high-impact vibrations common in quarries and crushing plants, guaranteeing stable operation even under extreme mechanical stress.
• Precision Digital Signal Processing (DSP):
  Microprocessor-controlled accuracy. Every signal is analyzed digitally for maximum stability. This allows for precise sensitivity adjustments and reliable performance in electrically noisy industrial environments.
• Smart Product Memory System:
  Switch products in seconds. Store up to 12 different product profiles. When changing materials on the conveyor, simply recall the preset parameters-no need for time-consuming recalibration.
• Seamless Plant Integration:
  Plug-and-play connectivity. Easily integrates with existing PLC systems. Features versatile relay outputs (NO/NC) to directly control alarm lights, horns, or automatic rejection devices without extra components.
