Frequently Asked Questions

Professional insights for industrial metal detection solutions

A walk through metal detector is an industrial security system that uses electromagnetic fields to detect metallic objects as people pass through a doorway-shaped frame. Our professional walk through metal detectors operate using dual-frequency continuous wave transmission technology.

The detection process works by creating intersecting electromagnetic fields that generate alerts when metal objects disrupt the field pattern. Our industrial metal detectors can detect objects as small as a paperclip while maintaining low false alarm rates in busy industrial environments.

Key technical capabilities include:

  • Detection sensitivity: Adjustable from 1-99 levels for different security requirements
  • Multi-zone detection: Pinpoint location identification across 6-18 detection zones
  • Environmental adaptation: Automatic ground balance for different installation locations
  • Integration capability: Compatible with access control and surveillance systems

Perfect for food processing facilities, pharmaceutical manufacturing, and high-security industrial applications.

Food processing metal detectors are specialized industrial metal detectors designed to identify and reject metal contaminants in food products during manufacturing. These systems are essential for preventing metal contamination that could cause serious injury to consumers and costly product recalls.

Modern food processing metal detectors use multi-frequency detection technology to identify three types of metal contaminants:

  • Ferrous metals: Iron, steel fragments from machinery wear, bolts, screws
  • Non-ferrous metals: Aluminum foil, copper wiring, brass fittings
  • Stainless steel: The most challenging to detect, requiring advanced technology

Our pharmaceutical metal detector systems meet FDA 21 CFR Part 11 compliance and HACCP requirements. The compact metal detector design integrates seamlessly into existing production lines without disrupting workflow.

Key benefits include automatic product rejection, data logging for traceability, and washdown-safe IP69K rated enclosures for sanitary environments.

Pharmaceutical metal detectors are purpose-built for the strict requirements of pharmaceutical manufacturing, featuring enhanced sensitivity, validation capabilities, and regulatory compliance that standard industrial metal detectors cannot provide.

Key differences include:

  • Ultra-high sensitivity: Detect metal particles as small as 0.3mm in tablets and capsules
  • FDA 21 CFR Part 11 compliance: Electronic records and signatures for pharmaceutical validation
  • IQ/OQ/PQ documentation: Complete Installation, Operational, and Performance Qualification packages
  • Sanitary design: Tool-free disassembly, crevice-free surfaces, pharmaceutical-grade materials
  • Product effect compensation: Advanced algorithms to handle conductive/magnetic pharmaceutical products

Our compact metal detector systems for pharmaceuticals include automatic test piece verification, audit trail capabilities, and multi-language HMI interfaces to meet global pharmaceutical manufacturing standards.

These specialized pharmaceutical metal detector systems ensure both product safety and regulatory compliance across all major pharmaceutical markets.

Compact metal detectors are space-efficient detection systems designed for applications where standard industrial metal detectors are too large or powerful. These smaller systems maintain high detection accuracy while fitting into constrained spaces and portable applications.

Common applications for compact metal detectors include:

  • Small production lines: Bakeries, specialty food processors, small-batch pharmaceutical production
  • Quality control stations: Sample testing, incoming inspection, laboratory analysis
  • Portable inspection: Field testing, temporary installations, mobile food service
  • Space-constrained facilities: Retrofitting existing production lines with limited floor space
  • Educational institutions: Training facilities, research laboratories, demonstration purposes

Our compact metal detector models offer the same dual-frequency technology and industrial-grade reliability as larger systems, with detection sensitivity suitable for small metal fragments and contaminants.

These systems feature intuitive touchscreen interfaces, automatic calibration, and integration capabilities with existing quality management systems.

Industrial metal detectors significantly improve production line efficiency by preventing contaminated products from reaching consumers, reducing costly product recalls, and maintaining continuous production flow with minimal operator intervention.

Key efficiency benefits include:

  • Automated rejection: Contaminated products are automatically removed without stopping production
  • Real-time monitoring: Continuous operation data and performance analytics
  • Preventive maintenance alerts: Predictive maintenance scheduling reduces unexpected downtime
  • Integration capabilities: Seamless connection with existing PLCs and factory automation systems
  • Multi-product memory: Store detection settings for different products to minimize changeover time

Modern walk through metal detector systems and conveyor-based industrial metal detectors feature advanced diagnostics that identify potential issues before they cause production delays.

ROI typically achieved within 6-12 months through prevention of recalls, reduced waste, and improved production efficiency.

Selecting the right metal detection system depends on your specific application, product characteristics, regulatory requirements, and operational environment. Each type of detector is optimized for different use cases.

Key decision factors include:

  • Walk through metal detectors: Best for personnel security screening, access control, and general facility protection
  • Food processing metal detectors: Essential for HACCP compliance, consumer safety, and brand protection in food manufacturing
  • Pharmaceutical metal detectors: Required for FDA compliance, GMP validation, and ultra-high sensitivity detection in drug manufacturing
  • Industrial metal detectors: Suitable for manufacturing quality control, raw material inspection, and general industrial applications
  • Compact metal detectors: Ideal for small-scale operations, laboratory use, and space-constrained environments

Our technical team provides free consultation to help determine the optimal metal detection solution based on your product specifications, throughput requirements, and regulatory compliance needs.

We offer demonstration units and trial periods to ensure the selected system meets your performance expectations before final purchase.
