The metal detector Syatem is designed to detect medium size and larges pieces of metal. The system has a very effective means of adiustig sensitivity. When used with the EM 600, 800, 1 000, 1200 amplifier, it well respond at the highest level of sensitivity to medium size parts like nails, washers, or pieces of flatware. When used used with the MDV amplifier, it will respond only to larger pieces of metal like teeth from an excavator bucket, tools, or metal paneling. If not discovered, these items could destroy stone-crushing machines, vibratory equipment, or wood-chipping machines. when used in this manner, the metal detector is suitable for protecting machinery, whereby smaller parts will not interrupt operation of the equipment. It detects mental dulk during bulk material transport by means of contactless measurement.
The System EM consists of an amplified and an inductive detector coil. The amplifier is equipped with an automatic adiustmen regulator that ensures reliable operation even when disturbing metal are in close proximity to the detector coil. In addition, the adiustment regulator also ensured that only metal parts that are in motion will be detected.
One of the amplifier's tasks is to process the signals emitted by the metal detector coil and convert them into an electronic pulse. The detector coil generates an electromagneti field.As soon as a piece of metal passes by the coil, it disturbs that field, restulting in a signal that can be evaluated.
The operator odiusts the mental detector's on the potrntiometer. The coil's sensitivity is dependent on several factors, including : The coils environment, the electromagnetic charateristics of the material to be detected, and the speed with which the mateial is transported.
