GOOD VIBRATIONS: TUNING INTO FOOD METAL DETECTION FREQUENCIES

摘要

The most widely used type of metal detector in the food industry functions on the principle known as the 'balanced coil'. With a general-purpose search head, these can detect ferrous and non-ferrous metals, as well as stainless steels in fresh and frozen products - either unwrapped or wrapped, even in metallised films. Yet, they are still unable to detect every particle of metal passing through them.
