Why does the vibration sensor have a magnet? What is the role?

The main function of the magnet is to move relative to the magnet within the working frequency range of the sensor, cut the magnetic line of force, and generate the induced voltage in the coil. The voltage value is proportional to the vibration speed value, which can be connected with the secondary instrument (vibration intensity monitor, vibration monitor, vibration transmitter, etc.) to display the vibration speed or displacement, and can also be transmitted to other secondary instruments The secondary instrument or AC voltmeter is used to measure, predict and alarm the mechanical failure.

Why use permanent magnets? What are the benefits?

The advantage of using permanent magnet is that it doesn’t damage the object to be measured and it is easy to move.
Attention should be paid to the installation position of the magnet vibration sensor: it should be installed vertically or horizontally on the vibration point to be measured, and the bottom of the sensor should be fixed with an M10 screw.
