You need to know about industrial metal detector sensitivity to keep your products safe and protect your customers. Sensitivity shows how well a detector can find small pieces of metal in food, medicine, and other items. High sensitivity is important because it helps stop dangerous recalls. For example, in January 2026, stores had to remove thousands of pizza and focaccia products because they had metal in them. In February, 9,462 pounds of meatballs were recalled for the same reason. Following strict safety rules like FDA, USDA, FSMA, and HACCP helps your business follow the law and keeps your products safe. COSO Electronic is a leader in the industry with new and trustworthy detection solutions made to keep you safe and give you peace of mind.

It is important to know about metal detector sensitivity to keep products safe. This means how well a detector finds metal pieces in things like food or medicine. You can check sensitivity by seeing if the detector finds a small test piece at the edge of its coil. If you set the sensitivity higher, you can find smaller metal pieces. This helps catch both ferrous and non-ferrous metals. You also need to think about the kind of metal, its shape, the size of the detector’s opening, and where you use the detector.
Metal detection sensitivity means the system finds metal contaminants but does not make mistakes.
It is most important in places where even tiny metal pieces can cause big trouble.
The kind of metal, how it is turned, the size of the opening, and the place you use it all change sensitivity.
Some people think sensitivity and detection capability are the same, but they are different. Sensitivity tells you how small a metal piece the detector can find. Detection capability shows what kinds of metals and shapes the detector can spot. If you set the sensitivity higher, you can find smaller pieces. This helps you catch more types of metals when you check products. You need to balance sensitivity so you do not get too many false alarms. If you set the detector too high, you may get too many mistakes. If you set it too low, you might miss dangerous metal pieces.
Tip: Always test your detector with different metals and shapes. This helps you know if your system works well for your products.
You need to follow industry standards to keep your products safe and follow the rules. There are no strict rules for the lowest sensitivity, but companies must make their own tests. The British Retail Consortium (BRC) says you must find metal pieces smaller than 1.5 mm in some foods. Other standards tell you how to use and check your detectors.
Standard | Sector | Key Requirements |
|---|---|---|
HACCP | Food | Find and control important spots for physical contaminants before packaging. |
IFS & BRC | Food | Use metal detectors; BRC says find pieces smaller than 1.5 mm. |
ISO 22000 | Food | Control physical dangers, trace products, and check equipment. |
GMP | Check for metal contamination at all steps; check and test often. | |
USP <232> & <233> | Pharmaceutical | Set limits for heavy metals and control impurities. |
You should check your detectors often and follow these standards to keep your products safe. This helps you stop recalls and keeps your customers happy.
You need to keep your customers safe from harm. High industrial metal detector sensitivity helps you find tiny metal pieces in products. This is very important for food and medicine companies.

You need to measure industrial metal detector sensitivity to keep your products safe. The best way to do this is by using test samples. These samples have a known size and type of metal. You should pass them through the center of the detector’s opening. This helps you check if the detector finds the smallest piece every time. The size of the opening, the product’s moisture, and the type of metal all change the results. Ferrous metals are easy to find, but non-magnetic stainless steel is harder. You should always use the smallest opening that fits your product to get the best results.
To keep your detector working well, you must calibrate it often. Here is a simple process you can follow:
Mark each test sample with its size and type.
Watch the detector as you run your product to see if anything interferes.
Write down the detector’s settings before you change anything.
Test each sample three times in the center of the opening.
Make sure the detector’s reject device works when it finds metal.
Change the settings if needed and record what you do.
You measure metal detector sensitivity in millimeters. This shows the smallest metal ball the detector can find. You set the sensitivity level based on the types of contaminants you want to catch. For example, you may need to find a 1.5 mm metal contaminant in bread. The sensitivity setting depends on your product and the risks. You must also think about irregular-shaped contaminants, as they can be harder to detect than round ones. You should always aim for the highest inspection sensitivity that does not cause false alarms.
You must check the accuracy of your detector often. Start by using real test samples and make sure the detector finds and rejects them. Test at different spots in the opening to cover all areas. Write down the product code each time you check. If the detector misses a sample, stop production and fix the problem. Check your test samples to make sure they are still good. Look at your records to spot any problems over time. You should test at the start of each shift, every few hours, and at the end of each run. Do a full check every week and review your results every month. Get a professional to check your detector once a year to keep your inspection system working at top accuracy.
The kind and size of metal pieces matter a lot. Ferrous metals are easier for the detector to find than stainless steel. The shape and direction of the metal also make a difference. For example, small round pieces are easier to spot than thin wires. Metal shavings or wires are harder to find because they are not round. Where the metal is as it moves through the detector can change what the detector finds. If you want your inspection system to be very sensitive, you should test it with many types and sizes of metal.
What your product is made of and how it is packed can change sensitivity. Some packaging, like thick foil, can block the detector’s signal. Moist food or salty food can make it harder to find metal. Packages with many layers or vacuum seals can hide small metal pieces. The thickness and shape of the package can also interfere with the detector’s field. When you buy a food metal detector, think about your product and its packaging so you get the right inspection.
The size of the detector’s opening, called the aperture, changes how well it finds metal. The center of the opening is the weakest spot for sensitivity. The edges are stronger. If the opening is big, the detector is less sensitive. You should use the smallest opening that fits your product. COSO Electronic makes detectors with different designs for many uses. Their systems help you by lowering false rejects and giving you good results.
Things like temperature and humidity can change how well your detector works. High humidity can cause water drops and make the detector give wrong readings.
