Plate Demagnetiser P 17

The P17 demagnetizers are normally installed in systems or under conveyor belts. This is a durable, moisture-protected installed device with a stainless steel casing. All operating voltages are available with 50 or 60 Hz. A lower frequency or pulse frequency will be used if there are problems. This may result in switch-on durations between 80 - 100%. Demagnetization can penetrate deeper than 0.5 mT (5 Gauss).

Why demagnetizing?
All the ferrous and ferromagnetic materials are capable of creating magnetic zones. This may occur with the raw material storage, with magnetic crack and hardness tests, cold forming, chip cutting, measuring or magnetic clamping and lifting.
Basically, magnetism is not harmful, but may prove interfering with further processing.
While demagnetizing, the magnetic field in the workpiece gets neutralised. The workpiece is magnetically neutral. The demagnetizing effect can be obtained by intense heating or a very strong external magnetic field. After demagnetization, the magnetic forces in the workpiece have disappeared. The magnetic field can be restored through remagnetization.
