Mechanical equipment vibration has a certain frequency. Traditionally, people refer to vibrations in the 50-300Hz frequency range as low-frequency vibrations, vibrations in the 300-1.8KHz frequency range as mid frequency vibrations, and vibrations above 1.8KHz as high-frequency vibrations. The measurement accuracy and sensitivity of different types of sensors vary. Universal sensors can be used for vibration measurement in high, medium, and low frequency bands, while low-frequency sensors are only sensitive to low-frequency vibrations. When the equipment vibrates, it will produce periodic changes in displacement, velocity, and acceleration. Acceleration sensors are used for vibration measurement, and the processed data spectrum can intuitively display the vibration of the equipment, thus completing the monitoring of the equipmentAcceleration sensors measure acceleration, and vibration sensors can also measure acceleration, but what is the difference between the two in measuring acceleration? If there is no difference, can I use a vibration sensor instead of an acceleration sensor?
