In highly developed modern industry, the development of modern testing technology towards digitization and informatization has become an inevitable trend. The front-end of the testing system is the sensor, which is the soul of the entire testing system. Especially in recent years, the rapid development of IC technology and computer technology has provided a good and reliable technological foundation for the development of sensors.
The role of sensors in industrial manufacturing cannot be underestimated. Machine condition monitoring is closely related to large-scale predictive maintenance programs. The goal of predictive maintenance is to reduce or completely eliminate sudden catastrophic machine failures by actively monitoring components that are critical to machine functionality. By monitoring components such as motors, fans, pumps, and other components such as bearings, tracking temperature and vibration parameters, and using algorithms to analyze the data collected in this way, faults can be avoided.
One of the most commonly used techniques in mechanical condition monitoring is vibration analysis. In short, vibration sensors are used to monitor the vibration of machines and machine components, with vibration sensors primarily monitoring the vibration of rotating machinery. Each device has its own vibration standard, and exceeding the vibration value indicates a machine malfunction, so vibration sensors can protect against vibration. Then, the vibration data will be further analyzed to determine whether there are deviations from normal operation, and whether and what intervention measures are needed.
Vibration sensors are widely used for mechanical vibration detection. A typical vibration sensor will measure the vibration of shafts and bearings of machine components such as motors and pumps. The vibration sensor itself is based on several different types of operating techniques, including the most common accelerometer based technology. Other vibration sensors are operated using strain gauges, microphones, pressure based sensors, or other types of measurement techniques.
