How to Choose a Food Conveyor Metal Detector: 4 Options from $1,167.95 to $6,256.00

When a metal contaminant slips into a food product, it becomes a quality and safety problem on your line. Conveyor-mounted metal detectors are the gatekeepers that catch ferrous, non-ferrous, and stainless steel fragments before they reach packaging. The challenge is picking the right one for your operation: How wide does your belt need to be? Do you want digital controls or a simpler setup? And are you open to a used machine to keep initial costs down? The four units here range in listed price from $1,167.95 to $6,256.00, so your decision depends heavily on your budget and what you expect the detector to do.

Quick Take

If you need a new, wide-belt machine with digital controls and a stainless steel body, the Industrial Digital Metal Detector Conveyor Belt (listed at $6,256.00) gives you the most capacity. For a smaller budget, the Mettler Toledo DMS 20 + EGK48-60NV (listed at $1,167.95) is a used option that includes the conveyor belt and detector unit, though it shows cosmetic wear. The INTBUYING and HayWHNKN units are new, 110V machines with similar SA-990 style features and sit close in price at $5,704.00 and $5,547.60 respectively.

Listed Price Comparison

The biggest price step is between the used Mettler Toledo unit and the new industrial machines. That gap reflects condition and feature level, so it is not just about saving money upfront-it is about what those extra features buy you.

Product Notes

Industrial Digital Metal Detector Conveyor Belt Food Metal Detection Machine

This is the most expensive option in the comparison, listed at USD 6,256.00, but it is also the one with the widest usable belt. The 450 mm food-grade white PU belt sits inside a 304 stainless steel body, and the conveyor length reaches 1600 mm. The seven-inch color touchscreen and digital signal processing system are designed for fast, precise detection, while the three-color tower light and audible buzzer give operators an immediate signal when contamination is found. Belt speed is adjustable from 20 to 40 meters per minute, which is useful if you process different product sizes. The main limitation is the price: it is the biggest upfront investment in this group, so make sure your line can justify the added throughput and control.

110VFood Conveyor Metal Detector Food Metal Detection Machine Inspection Machine

Listed at USD 5,704.00, this INTBUYING unit is a new, 110V machine that fits into a standard U.S. power setup. The SA-990 model is described for industrial use in food, agriculture, plastics, textiles, and similar sectors, so it is a versatile choice if you need one detector for multiple product lines. It can detect iron and non-ferrous metals like copper and aluminum, which covers the most common contamination risks. The limitation here is the 110V requirement: if your facility is wired for 220V or other voltages, you will have to factor in an electrical adjustment or transformer before it can run on your floor. The listed price is also close to the higher end of this group.

Mettler Toledo DMS 20 + EGK48-60NV EG Metal Detector Conveyor Belt

This is the only used unit in the group, and its listed price of USD 1,167.95 makes it the lowest-cost entry point into a full conveyor metal detection setup. The Mettler Toledo name appears on the equipment, and the item description says the external condition is good, the unit works, and it comes as a single batch. The honest caveat is visible wear: the description notes discoloration and ink marks on the unit. Unless your line is brand-new, that kind of cosmetic condition is unlikely to affect detection, but you should be comfortable buying a used piece of machinery. If you are installing a first inspection point or building a line on a limited budget, this is the one to weigh against the new machines.

Industrial Food Conveyor Belt Metal Detector 110V 400mm Width Fe Φ≥1.0mm

At USD 5,547.60, this HayWHNKN machine is the second-lowest priced new unit in the group. Its standout spec is the explicit iron detection threshold: Fe Φ≥1.0mm, which means the detector is rated to catch iron spheres at or above that diameter. That makes it a concrete choice if your quality checklist requires a specific iron sensitivity number. The conveyor belt width is 400 mm, which is a little narrower than the 450 mm on the first machine, but that may be fine for smaller product formats. Like the INTBUYING model, it is a 110V machine, so voltage compatibility is a consideration before you commit.

Final Recommendation

If you want the most capable new machine and have the budget for it, the Industrial Digital Metal Detector Conveyor Belt at USD 6,256.00 is the one to choose. Its wider belt, stainless steel construction, and digital touchscreen make it a strong fit for a food production line that runs varied product sizes. If you need a specific iron detection rating and a 400 mm belt, the HayWHNKN Industrial Food Conveyor Belt Metal Detector at USD 5,547.60 gives you that spec for slightly less money. The INTBUYING unit at USD 5,704.00 is a similar new alternative with the SA-990 model designation. And if your priority is keeping upfront cost low, the used Mettler Toledo DMS 20 + EGK48-60NV at USD 1,167.95 is the clear budget pick, provided you accept its cosmetic flaws.
