Loma highlights the importance of metal free zones for ensuring optimum metal detector performance

摘要

Loma Systems - leading manufacturer of advanced metal detectors, checkweighers and X-ray inspection equipment for the global food industry - is highlighting the importance of Metal Free Zones for ensuring optimum performance of its IQ4 Metal Detectors. The Metal Free Zone is an area surrounding the aperture of a metal detector that should be kept free of any fixed or moving metal to avoid a spike in the signal that could cause false rejects and costly downtime. The spike can be random or follow a pattern depending on whether moving or non-moving metal is causing the issue. It might also produce symptoms like that of a contaminated belt or walkie talkie use. The calculation of a Metal Free Zone varies and depends on two key factors: is it moving or non-moving metal? The only exception to this rule are gravity fed metal detectors that are integrated into fill and seal baggers with a chute going through the aperture.
