Main function of the magnet is within the scope of the sensor working frequency, relative movement between coils and magnets, cutting lines, to produce induced voltage in the coil, the voltage is proportional to the vibration velocity values, and secondary instrument match (vibration intensity monitors, monitors, vibration transmitter, etc.), can show the size of the vibration velocity or displacement. It also can be transmitted to other secondary instruments or ac voltmeters for measurement, used to predict and alarm mechanical failure.
The advantage of using permanent magnet is that it does not destroy the object under test and it is easy to move.
Attention should be paid to the mounting position of the magnet vibration sensor: it should be installed vertically or horizontally on the vibration point under test, and the bottom of the sensor should be fixed with screws.
