Metal detectors are precise measurement devices. When working with metal detection in the food and pharmaceutical industries, there are many common issues that we see. Food metal detectors are often found in harsh plant conditions. Many other pieces of equipment come together to form the processing line, and often, metal detectors are inserted into the line in multiple different locations. At different places in the line, some issues are more present than others. For all metal detectors, when these issues are encountered, changes need to be made to allow the metal detector to function properly.
