Metal Detectors
Conveyor, gravity-fall, pipeline and pharmaceutical metal detectors for ferrous, non-ferrous and stainless steel, plus models for foil-packed products.
PSG NOW multi-frequency metal detectors for every way product moves: packs on a conveyor, powders falling through a tube, pumped meats and sauces, tablets and capsules, and foil-packed goods.
- 7 frequencies on the NMD580
- IP66 washdown rating on the NMD580
- 50 product presets on the NMD500
Start with how your product moves
The NMD580 SEEKER is the flagship of the range: seven selectable frequencies plus a mixed mode, an IP66 washdown rating, and conveyor, pharmaceutical, fall and pipeline versions.
Conveyor
Packaged products. NMD-530 Conveyor for belts 200 to 600 mm wide at up to 60 m/min; the NMD500 series covers lines up to 28 m/min in six head sizes.
Gravity-fall
Powders and granules. NMD-530 Fall Type for tubes 50 to 150 mm in diameter and up to 20 tons an hour, before the product is packed.
Pipeline
Pumped products. NMD-530 Pipe Line for meats, slurries and sauces, from 80 mm pipe, rejecting through a ball valve.
Pharmaceutical
Tablets and capsules. A dedicated NMD-530 model for tablet and capsule lines, with a password-protected detection history.
Aperture size and sensitivity
A metal detector is most sensitive when the aperture is only as big as the product needs, so choosing the head size matters as much as choosing the model. The NMD500 series comes in six: 350 × 100 and 350 × 150 mm heads on a 300 mm belt, and 450 × 150, 450 × 180, 450 × 200, and 450 × 250 mm heads on a 400 mm belt.
Wet, salty, or warm products such as cheese, meat, and pickled foods can produce a signal of their own, known as product effect. Multi-frequency detectors are built to separate that signal from real contaminants. The NMD580 adds product-effect tracking, and the NMD500 series stores 50 product presets so operators can change SKUs without re-tuning.
Foil and metalized packaging
Aluminum caps, metalized pouches and retort packs look like metal to a standard detector, so the NAD4000 family is built for them. If foil-packed products also carry glass, stone or bone risks, compare these with an X-ray inspection system.
NAD4000 Standard-AB
Dual A/B detection. Reliable results through metalized film.
NAD4000 Economy
Entry point. The lower-cost way into foil detection.
NAD4000 Alcon Combi
Automatic reject. Adds an automatic reject conveyor.
NAD4000 Composite
With checkweigher. Pairs foil detection with a checkweigher on a single 2,300 mm conveyor.
Rejects, records, and combination units
A detector is only as useful as what happens when it alarms. Across the range you can choose belt stop with an audible alarm and tower lamp, an automatic reject conveyor, or a ball-valve diverter on pipelines. The NMD-530 pharmaceutical and pipeline models keep a detection history behind password protection for audit trails.
Short on floor space? The NCB 450/490 Combi detects ferrous metal down to 0.5 mm, non-ferrous to 0.8 mm, and stainless steel to 1.0 mm while checking weights from 5 g to 3 kg in one compact unit. The NWC3000 Combi pairs a high-speed checkweigher with a metal detector inline.
