Metal Detectors

Metal detectors can be used throughout the food production process in order to protect consumers by detecting metallic contaminants and preventing the contaminated food from ending up on retailers' shelves. Food metal detectors can also be used in line to protect other machinery that is downstream.

How is a metal detector made: A metal detector contains a coil of wire (wrapped around the circular head at the end of the handle) known as the transmitter coil. When electricity flows through the coil, a magnetic field is created all around it. As you sweep the detector over the ground, you make the magnetic field move around too.

How do you test for metal in food: Basically there are several types of metal detectors that operate with different detection methods. 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.

What metals Cannot be detected by a metal detector:
One of the most difficult metal to locate with a metal detector is stainless steel because steel has poor electrical conductivity and also has low magnetic permeability.
Other items that cannot be detected with a metal detector include: Pearls. Diamonds. Paper. Stone figurines. Bones. Liquid. Glass. Plastic.
How deep can a metal detector detect: six to ten inches.
A typical good quality machine can detect six to ten inches below the ground for coin-sized objects. However this highly depends on many factors.

Scrap Metal Classifications: What Are The Different Types of Scrap Metal:
Non-Ferrous. Non-ferrous metals don't contain iron so they aren't magnetic and they're typically more corrosion and rust resistant than ferrous metals.
Aluminum. Aluminum is one of the most commonly recycled scrap metals.
Brass. Carbide. Iron. Lead.

Where can I metal detect coins:
The Best Metal Detecting Sites for Old Coins and Rings.
Historic Homes. I've gone treasure hunting at several different places, but one of the best metal detecting sites for me has always been permissions at old homes, preferably those built before 1900.
Old House Sites (Torn Down). Old Swimming Holes. Old Churches. Old Parks.
What are the best places to metal detect:
Your Yard. Your back yard might not be the most exciting place to search for treasure, but it's a great place to test a new detector and drill that smooth, long sweep.
Land Owned by Friends and Family. Sports Stadiums. Parks. Beaches.
Prospect for Gold in Known Hunting Grounds. Churches. Battlefields.

Best metal detectors.
Garrett AT Pro: best value all-around, coins, relics, freshwater.
Fisher F22: best entry-level, kids, coins.
Minelab Equinox 800: best relic hunting.
Minelab Excalibur II: best for saltwater and beach hunting.
Minelab CTX 3030: best of the best.

Production of metal detectors is metal related business that an entrepreneur can successfully start. Where terrorist attack is at its peak, it is necessary to screen cars and people in public places and this is done with the aid of metal detectors.

A metal detector is an instrument that gives a signal when it detects the presence of metal and they are also used to detect the presence of stray bits of metal in food products or to find buried metal.
