How sensitive is your food metal detector?

摘要

Theoretically, many variables will determine the sensitivity of a food inspection metal detector. Among them the aperture size - the smaller the aperture, the smaller the piece of metal that can be detected, the type of metal - ferrous, non-ferrous or stainless steel, product effect, and the orientation of metal contaminants as they pass through the detector. Environmental conditions, such as airborne electrical interference, vibration and temperature fluctuation may also affect performance.
