Magnetic reluctance magneto electric speed sensor

I. Overview

Magnetic electric speed sensor uses the principle of electromagnetic induction to achieve speed measurement. It can measure the speed of various magnetic materials such as gears, gear discs, perforated and grooved (concave convex grooves, healthy phase grooves), magnetic steel, optical axis (attached magnetic plates), disks, etc. without power supply or contact, and convert it into frequency signal output (sine wave signal).

2、 Application Fields

Magnetic electric speed sensors can be widely used in large rotating machinery in the power, metallurgy, petrochemical, shipbuilding, and paper industries (such as measuring the speed and overspeed of steam turbines, compressors, motors, fans, pumps, etc.)

3、 Characteristics

No power supply required, simple installation

Non contact measurement

Strong output signal

Strong anti-interference ability

Suitable for harsh industrial environments such as smoke, oil and gas, and water vapor

4、 Introduction:

Magnetic reluctance speed sensor is a cost-effective and widely used universal speed sensor, used for measuring the speed of magnetic objects, using non-contact measurement method. 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.

5、 Performance characteristics

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.

Gear Module ：2to 4 face widthb: Greater than5mm.
