EGE metal detectors are reliable and robust. They are designed for outside applications in harsh climates. The metal detector System 3000 is designed to detect medium-sized and larger parts. The system has a very effective sensitivity setting. Together with the amplifier MU 3300, it responds to medium-sized parts such as nails, nuts or pieces of flatware when set to the highest sensitivity setting. Together with the amplifier MDV, it only responds to larger metal parts such as the teeth of an excavator shovel, equipment or tool parts or paneling. Such parts could damage stone-crushing machines, vibratory equipment, or wood-chipping machines. When used in this manner, the metal detector is suitable for protecting machinery by preventing that larger parts interrupt operation of the equipment. It detects metal during bulk material transport by means of contactless measurements.
