Metal Detectors Metal Inspection Systems

It is widely accepted that Metal Detectors are an integral part of almost all Food, Confectionery, Bakery, Snack processing and Pharmaceutical lines. Loma-Lock sets the industry standards in metal detection. Loma-Lock metal detectors find ferrous and non-ferrous metal particles. Loma-Lock systems can also be used to find ferrous metals while ignoring the non-ferrous metals, to indicate when there is iron contamination in the product.

Metal detection is born out of necessity and is unlikely to have occupied more than a fleeting thought in most manufacturers' minds. Loma-Lock provides state-of-the-art Metal Detectors with advance Digital Control

For over 50 years Loma-Lock has supplied metal detectors to customer’s worldwide, providing reliable detection, day after day, in products as diverse as biscuits, chocolates, raw meat and prescription drugs.

LOMA-LOCK INSPECTION SYSTEMS is the world’s leading manufacturer of metal detection systems for the Food, Pharmaceutical and Packaging Industries. Faced with the challenge of developing an all new range of metal detectors for food manufacturing and packaging, Loma Lock‘s R&D team were handed a simple brief - design a product to set new standards for good manufacturing practice, efficiency, product quality, traceability and compliance with existing and forthcoming legislative and regulatory requirements.

  • Detection and removal of metal contamination from incoming raw materials and formulations prior to processing and manufacture
  • Unrivalled product and brand protection
  • Choice of multi-frequency search heads available from 30 to 1MHz
  • User-friendly operation including auto-setup INSIGHT metal detectors are available with a full range of systems and reject options including full fail-safe specifications comprised of reject confirmation, air failure alarm and bin full alarm
  • Compact design allows easy integration with all well known brands of inspection and packaging machinery
  • Data storage for up to 8000 events
  • Data reports can be downloaded to a standard memory stick or PC to enable the secure storage and distribution of quality records in PDF or other formats



Metal detection equipment needs to be installed at designated critical control points according to HACCP principles. Contamination from broken sieves, blades, bearings and damaged milling equipment will be detected at these stages.

High Sensitivity: Extremely resistant to vibration, the INSIGHTs Integrated Digital Search Head and sophisticated signal processing software is capable of filtering out even the most complex product signals in order to detect and reject minute fragments of metal. Locks unique coil design and signal processing capability offer particularly high sensitivity to stainless steel.

Fail-safe: Product integrity is fully protected by the INSIGHT during power fluctuation or interruption. “Test prompt” software ensures adherence to quality systems.

Hygiene: The INSIGHT range is sealed to IP69k/PW12 from approved materials which allow full wash down where required to provide necessary levels of cleanliness.

LOCK Insight HD

The INSIGHT HD range of metal detectors for the food and packaging industries sets new standards for good manufacturing practice – specifically - traceability, efficiency, product quality, and compliance with existing as well as forthcoming regulatory requirements.

To achieve these goals metal detection and signal processing take place in the compact INTEGRATED DIGITAL SEARCH HEAD. Sophisticated OPTIX detector management software uses Lock’s unique DDS (Direct Digital Signal) vector diagram to generate the detailed product profile needed to achieve perfect product set-ups. This guarantees detection and rejection of metal fragments in both conductive and on conductive product applications while achieving stable operation and market leading sensitivities to all metals.
