Sensitivity Requirements
The equipment must achieve the following:
Sensitivity must be stable and require infrequent adjustment
Not reject good product or provide false positive results
Be capable of detecting metal in various orientations relative to the detection head
It is important to work with your equipment supplier in determining and establishing these conditions. Sensitivity levels must be realistic and attainable and your supplier will be best placed to provide guidance. In some cases customer technical standards will also provide suggested sensitivity
levels for their products. The following are sample sensitivities (mm) based on pack size

What are the considerations for purchasing a metal detector?
Decide what types of metal you need to detect. There are two main categories of metal: ferrous and non-ferrous. Ferrous metals are derived from iron or contain iron. Non-ferrous metals are all others. Take a careful inventory of the types of metal in your operation that could possibly end up in your products.
What sizes of metal contaminants do you need to screen for? You need to be practical and realistic with this question because if you specify too much sensitivity, you will get too many false alarms and vice versa.
Know the operating environment and the product characteristics – The operating environment includes the temperature and whether water, dust, or chemicals could come in contact with your metal detector, as well as possible electrical fields. Additionally, is the product fresh or frozen, packaged or exposed, scanned individually or in a case? All of these factors will go into the design of a metal detector that will fit your needs the best.
Reject System considerations – Most commonly, a pusher or an air blast is used to divert products where metal has been detected. However, you could save space by having the conveyor belt stopped and a warning light activated. Additionally, an optional Lockable Collecting Container prevents unauthorized employees from gaining access to rejected product.
