The YD9300 series low-frequency vibration speed sensor belongs to inertial sensor. It is mainly composed of magnetic circuit system, inertial mass and spring damping. YD9300 uses magnetic induction principle to transform vibration signal into electrical signal. Compared with other types of vibration sensors, YD9300 has lower output impedance, better signal-to-noise ratio and certain anti-equation vibration capability; the frictional movable components are eliminated in the design, and the service life is long; same as the universal AC voltmeter or The oscilloscope can work together, and has no special requirements on the output plug and transmission cable, and is convenient to use.

YD9300 is suitable for low frequency, especially for low speed motors.

Further information
Features and Advantages
	● Lower output impedance ● Good signal to noise ratio ● Has a certain ability to resist vibration ● Frictionless components for long service life
Applications
	Low frequency vibration sensors can be used in many areas: · Earthquake monitoring; engineering geological exploration; · Hydraulic generator set vibration monitoring; · Modal testing and dynamic deflection measurement of large buildings and bridges; · The road and rail irregularity of the railway are measured, the vehicle is shaken, and the vehicle is derailed to the police; · Burglar, perimeter alert; and so on. The low frequency vibration sensor is mainly used to measure the vibration of hydroelectric generating sets, low speed rotating machines, engineering buildings and bridges. The vibration measured by the sensor is the absolute vibration relative to the free space. Its output voltage signal is proportional to the amplitude of the vibration.
