SZCB-01-01-080-00-03 Magnetic Resistance Speed Sensor

The large working mode of SZCB-01 magneto electric speed sensor determines its strong anti-interference ability, which can work in environments such as smoke, oil and gas, water vapor, etc. The output signal of the magneto electric speed sensor is strong and has a wide measurement range. It can measure components such as gears, crankshafts, spokes, and rotating bodies with gaps on the surface.

The maintenance cost of SZCB-01 magneto electric speed sensor is relatively low, and the operation process does not require power supply. It relies on magneto electric induction to achieve measurement. At the same time, the operation of magneto electric speed sensor does not require mechanical action or lubrication. The magnetic electric speed sensor has a compact structure, small size, and easy installation and use, and can be used in conjunction with various secondary instruments.

The SZCB-01 reluctance speed sensor uses the principle of electromagnetic induction to achieve speed measurement. It has the advantages of not requiring an external power supply, having a large output signal, and being easy to use. Can be used in environments with relatively harsh conditions such as smoke, oil and gas, water and gas, explosion-proof, etc.

I. Overview

The SZCB-01 magneto resistive speed sensor 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.

3、 Gear requirements
Gear material: Gear materials should be made of metal materials with strong magnetic conductivity.
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 measurement. If there is axial movement of the spindle, it should be noted that the center of the magnetic pole should be at the center position of the gear.
