Details

A metal detector is an inspection device used to identify ferrous and non-ferrous metal contaminants in production lines. It operates on electromagnetic induction. A central transmitter coil generates a high-frequency magnetic field balanced by two receiver coils. When a metal particle enters this field, the balance is disrupted, generating a signal that triggers an alarm or activates a rejection mechanism. Modern units use digital signal processing for high sensitivity and stability. They are widely applied in food, pharmaceutical, cosmetic, textile, feed, and chemical industries to ensure product safety and protect processing equipment from metal damage.

Core Advantages

Detects ferrous, non-ferrous, and stainless steel contaminants with high sensitivity

Triggers audible and visual alarms or automatic rejection upon detection

Reduces product contamination risk and protects downstream machinery

Features self-check function and product effect compensation for wet or salty products

Constructed with stainless steel for easy cleaning and corrosion resistance

Offers various rejection systems including push arm, air blast, flap

Product Features

This metal detector features a balanced coil detection head, digital signal processor for stable performance, and an intuitive touchscreen interface for easy operation. It includes product effect adjustment to minimize false alarms from conductive products. The stainless steel frame meets hygiene standards, and selectable detection modes adapt to dry, wet, or high-moisture products. Available rejection mechanisms ensure contaminated items are removed from the line without stopping production.

Product Applications

This metal detector is suitable for inspecting bulk products, packaged items, free-falling powders and granules, as well as liquid or paste products. It is widely used in food processing, pharmaceutical manufacturing, cosmetic production, textile and garment industries, feed milling, chemical material handling, and rubber or plastic processing lines.

Precautions

Clean the detector surface regularly. Do not install near strong electromagnetic sources. Verify sensitivity daily using standard test balls. Avoid wet environments unless rated with high ingress protection. Disconnect power before cleaning or maintenance. Train operators to respond to alarms correctly.

FAQ

Q: What is the difference between a metal detector and a checkweigher?

A: A metal detector finds metal contamination using electromagnetic fields. A checkweigher measures product weight. Some integrated systems combine both functions, but they are fundamentally different devices for different purposes.

Q: Can this machine detect all types of metals?

A: Yes. It detects ferrous metals like iron, non-ferrous metals like copper and aluminum, and stainless steel. Sensitivity varies by metal type, particle size, and product characteristics.

Q: How often should I test the detector's sensitivity?

A: Test before each production shift and after any product changeover. Use standard metal test balls of specified diameters (for example, iron and stainless steel). Record results for quality assurance and safety audits.
