Metal Detector IQ 2 Loma previously used for Butter blocks 20 kg

This is a LOMA Systems IQ-series industrial metal detector, commonly used in food and dairy processing lines. Here’s a clear, practical breakdown of what it is and what it does.

Its job is foreign body detection — specifically metal contamination — to protect:

• Product safety
• Equipment (pumps, fillers, valves)
• Brand and compliance (HACCP, BRC, IFS, etc.)

You’ll typically find these on:

• Dairy products (cheese, butter, powders)
• Ready meals
• Meat & poultry
• Bakery
• Packaged foods on conveyors

What metals it detects

The IQ range detects all three common metal types:

• Ferrous (iron, steel)
• Non-ferrous (brass, aluminium)
• Stainless steel (the hardest to detect in food environments)

Sensitivity depends on:

• Aperture size
• Product type (wet/dry, salt content)
• Conveyor speed
• Calibration

The LOMA IQ control system

The LOMA IQ® controller you showed is the heart of the machine.

Key features:

• Digital signal processing (very stable, low false rejects)
• Product memory presets (quick changeovers)
• Automatic calibration
• Password protection (QA / operator levels)
• Event & fault logging (useful for audits)
• Reject confirmation & fail-safe monitoring

This is why LOMA machines are popular in regulated food plants.

• Conveyor metal detector with integrated electronics
• Stainless steel construction (washdown suitable)
• Reject output (air blast, pusher, stop-on-detect — depends on configuration)
• Industrial power supply (as per the data plate)

The data plate confirms:

• 415V 3-phase + neutral
• 240V single-phase control circuit
• UK-manufactured (LOMA Systems, Hampshire)

Why buyers like these

• Extremely reliable
• Easy to validate and document
• Long service life
• Strong resale value
• Widely supported (spares & engineers)

That’s why they’re common on the used dairy machinery market.
