4、 Introduction:

Intelligent speed monitoring device WZ-3CIt is a cost-effective and versatile universal speed sensor used for measuring the speed of magnetic objects, using non-contact measurement methods. The sensor is composed of magnetic steel, soft magnetic armature, and coil inside. The basic measurement principle is that the magnetic field (magnetic lines) is emitted by a magnet and passes through the armature and coil. When a magnetic object approaches or moves away, the magnetic flux in the coil changes,Changes in electromotive force induced by coils,Speed measuring gear on the inner shaft of the coil),Frequency signal proportional to induction and rotational speed; If it is an involute gear,The induced voltage is a sine wave. The amplitude of the signal is directly proportional to the rotational speed,The gap size between the probe end face and the tooth tip is inversely proportional.

Gear material: Gear materials should be made of metal materials with strong magnetic permeability.

Tooth profile: Forming an involute tooth profile is the most suitable tooth profile. Using large modulus gears or other tooth profiles will result in significant waveform distortion, which will hinder accurate measurements. If the spindle has axial movement, it should be noted that the center of the magnetic pole should be at the center position of the gear.
