Metal detector testing tips: Ensuring your metal detector gives the protection you expect
How do you test your metal detectors? While throwing a metal test sample into your processing or handling system to see if the metal detector gives a reassuring beep is easy and straightforward, this method has little value in a properly organized quality check. Following the procedure outlined here will help you get the protection you expect.
You need different procedures to check a conveyor belt metal detector that inspects bags and packages and a gravity-feed metal detect that inspects free-flowing bulk solids. In either case, your test needs to confirm that the detector always detects the metal and always accurately rejects it. The latter is often overlooked and is a major source of metal detection program failures.
