Glossary

Aperture: The area through which product is passed.

AutoBalance: A patented detector feature that automatically makes balance adjustments

for each of the 70 available frequencies to provide optimum detector

performance.

Bin Full: Option which uses a PEC to indicate when a reject bin is full and needs to

be emptied.

Conductivity: The measured amount of eddy current generation created on a metal

surface.

Detector Performance: Relates to how well the metal detector can reliably detect metal

contaminants,

Eddy Current: Small circulating electric currents generated when an electromagnetic field

contacts the surface of a metal object. Secondary electromagnetic fields

are generated by these currents and picked up by the receiver coils. This

causes an inductive imbalance to occur between the transmitter and

receiver coils which is used to identify and reject contaminated products.

Electromagnetic Field: An invisible electrical field emanating from a transmitter coil. This field is

generated by the flow of alternating oscillator frequency current around the

transmitter coil's windings.

False Triggering: Product rejects caused by external effects and not by a contaminant in the

product itself.

Ferrous: A metal mainly composed of iron which also has magnetic properties.

Frequency: The number of alternating current cycles per second (Hz) produced by the

transmit oscillator. The metal detector's electromagnetic operating

frequencies are measured in Kilohertz (kHz). Low signal frequencies

penetrate the product deepest, but sensitivity to smaller targets is low.

Higher frequencies have a more shallow detecting depth but high

sensitivity to small targets.

GUI: The controls used to set up and operate the metal detector.

Learn: The process of passing sample products through the metal detector so

that it can automatically select the optimum detector settings based on the

product effect.
