Metal Detection - Overview

The correct operating frequency is key to the detection of metals used in the food, pharmaceutical and packaging industries. The award-winning Loma IQ3 and IQ3+ range of metal detectors are the first to offer true variable frequency, operating between 40 - 900 kHz. The IQ3 and IQ3+ series selects the correct operating frequency in seconds, eliminating past performance restrictions caused by limited frequency metal detectors. Changes in products or packaging that necessitate a frequency change no longer require the expense and inconvenience of operator intervention.


All Loma IQ3 and IQ3+ metal detectors are UL and CUL approved, the first and only systems on the market to attain this approval.

Ultra Harsh Environments

Rapid temperature changes, vigorous and caustic wash-down regimes, high humidity and saline environments are just some of the factors that can take a toll on even the toughest environmental standards.

To provide added peace of mind in these harsh environments, Loma offers ultra-harsh metal detector search heads in the IQ3 and IQ3+ series. Advanced construction consisting of 304L stainless steel, polymers and resins create water and dust tight seals – perfect for improving sanitization, preventing erosion and combating thermal shock. The IP69K rating ensures you have the most rugged system for your demanding environment.

Maximum Stability

A unique case and coil geometry delivers a quantum leap in immunity from interference caused by vibration, electricity, case distortion and thermal shock.

Built Reliable

304L stainless steel, polymers and resins create water and dust tight seals to ensure system stability. All metal detectors are constructed with an angled frame combined with Allen Bradley motor controls.

Intuitive Controls

The IQ3+ control panel comes with a color touch screen and has intuitive, icon-driven menus with context sensitive help screens.

Automatic Product Learn

Automatically learn the characteristics and settings for up to 100 different products for rapid product change-over.

Enhanced Performance Validation System (PVS)

PVS automatically prompts for performance testing according to HACCP guidelines. PVS does not rely on manual test verification and only uses pre-specified test samples. This feature ensures test results cannot be falsified.

Contaminants Log

Right from the dashboard, identify when contamination was detected as well as the size of the contaminant. The contaminants log is essential for tracing the contaminant source.

Secure Access

Select the level of access for operators and key personnel and enable password protection to restrict unauthorized access to the operating system.
