How do metal detectors work in food industry?
In the food industry, metal detectors usually apply the transmitter-receiver method (see graphic). Such metal detectors are equipped with a transmitter coil and two receiver coils. The transmitter coil generates a constant electromagnetic field.

What do hand held metal detectors detect?
Handheld metal detectors are designed to detect suspect items that contain metallic components, such as weapons or illicit contraband.
Are metal detectors safe for food?
Similar unpredicatable performance can exist when attempting to detect metals in food. Metal detection is simple when it works, but difficult when it does not. Detectable metal sizes and types may not be what the quality manager needs. Audits can fail.
Do handheld metal detectors work?
High quality hand held metal detectors will find concealed knives and weapons, foil wrapped drugs and other concealed metallic objects. When using a hand held metal detector it’s important to understand that they are motion detectors, which means that they will not raise an alarm if held stationary.
What are food metal detectors?
Metal Detection for Food Contaminants Metal Detectors sense and remove the presence of ferrous, nonferrous and stainless metals in a process flow, or as a packaged item. All food-grade (or higher) come standard with Metal-Detectable Gaskets & Grommets for an added layer of product safety and brand protection.
What is the critical limit for metal detection?
The FDA’s Health Hazard Evaluation Board has outlined that metal fragments 0.3 inch – 1 inch (or 7mm – 25mm) in length are unacceptable if found in any products. And any foreign object less than 0.3 inch (7mm) can cause serious injury to people in special risk groups, such as infants, surgery patients and the elderly.
What is the hobby of metal detecting called?
TH’ER (TREASURE HUNTER) TH’er is an abbreviation for Treasure Hunter and refers to an enthusiast in a hobby of metal detecting and treasure hunting. Often also known a a Detectorist.
When did metal detectors become popular?
1960’s
The 1950’s and 1960’s saw metal-detecting becoming much more popular as a hobby, and smaller devices were developed that people could carry with them. People who enjoy looking for metals can be in search of any number of different items.
Where do you find metal in food?
Metal detectors use electromagnetic fields to find things that are magnetic and conductive. Most food products are wet, have salt or contain minerals, which when subjected to electromagnetic fields also look magnetic and conductive. Ignoring the product and finding the metal is not as easy as it seems.
Are hand held metal detectors safe?
Background: Case reports suggest that the hand-held metal detectors used for security screening generate electromagnetic fields that may interfere with pacemaker and implantable cardioverter-defibrillator (ICD) function.
What is industrial metal detector?
CEIA Metal Detectors detect metal contaminants accidentally present in industrial products with levels of sensitivity, immunity to interference and response speeds exceeding the strictest Quality Control Standards.
