What are the typical applications of vibration sensors

Vibration sensor is a widely used alarm detection sensor. It senses the parameters of mechanical motion vibration (such as vibration speed, frequency, acceleration, etc.) through the internal piezoelectric ceramic plate and spring weight structure, and converts them into available output signals. Then it is amplified and output control signals through LM358 and other operational amplifiers.

What are the typical applications of vibration sensors

Vibration sensors can be used for long-term monitoring of vibration and displacement in machinery, thermal expansion of rotor and casing, on-line automatic detection and automatic control of production line, and measurement of many kinds of micro-distances and Micro-motions in scientific research.

Vibration sensor is one of the key components in testing technology. It has the advantages of low cost, high sensitivity, stable and reliable operation, and large adjustable range of vibration detection. It is widely used in many fields such as energy, chemical industry, medicine, automobile, metallurgy, machine manufacturing, military industry, scientific research and teaching, etc.

What are the typical applications of vibration sensors

Vibration sensors can monitor the vibration of car body in special frequency band, and alarm can be generated when the car body is damaged by external force. If someone hits, hits or moves your car, the sensor sends a signal to the controller indicating the vibration intensity.

What are the typical applications of vibration sensors

Depending on the intensity of the vibration, the controller will issue a "beep" or a full-scale alarm. Many advanced alarm systems use vibration sensors as the preferred anti-theft device, but they are usually used in conjunction with other devices. At present, 80% of vehicle alarms in automobile and motorcycle anti-theft systems use such sensors.

Application of Vibration Sensor in Pump House Unit Equipment

With the rapid development of science and technology, the degree of mechanization of machinery industry is also increasing rapidly. The mechanical equipment of modern industrial production is gradually becoming more complex, high-speed and automated. In order to grasp the operation status of equipment and avoid accidents, people pay more and more attention to the on-line monitoring and fault diagnosis of key units in production. Vibration sensor undertakes this important task and ensures the normal operation of the equipment.

What are the typical applications of vibration sensors

When vibration occurs in pump house or unit, it is necessary to use vibration sensor to measure and analyze the possible causes of vibration one by one, find out the crux of the problem, and then take effective technical measures to eliminate it.

Industrial vibration analysis technology is a detection tool for identifying, predicting and preventing rotating equipment faults. Implementing equipment vibration analysis will improve the reliability and efficiency of equipment, reduce downtime and eliminate mechanical and electrical faults. Vibration analysis technology is a universal tool for determining equipment failure, setting equipment maintenance plan, and making equipment work as long as possible.

What are the typical applications of vibration sensors

The rotating components of these devices have their own specific vibration frequencies. The vibration amplitude represents the working condition or quality of the equipment. Amplitude enlargement directly indicates the failure of rotating components such as bearings or gears.

For rotating machinery, the main analysis signals are vibration signals. For pumps, an important feature of pump failure is that the machine is accompanied by abnormal vibration and noise. The vibration signal can reflect the fault information of the pump in real time, and the vibration sensor can monitor the operation status of the pump in real time, so as to detect the fault information at the first time, inform the maintenance personnel to take measures to ensure the normal operation of the pump, improve work efficiency, and eliminate potential safety hazards.

Application of Vibration Sensor in Modern Industrial Production Line

Precision industrial production process is increasingly dependent on the efficient, reliable and consistent operation of motor and related machinery and equipment. The unbalance, defect, fastener loosening and other abnormal phenomena of machinery and equipment often translate into vibration, which leads to the decrease of accuracy and safety problems. If left unchecked, besides performance and safety problems, it will inevitably lead to productivity losses if the equipment is shut down and repaired. Even if the performance of the equipment changes slightly, it is usually difficult to predict in time and can quickly translate into significant productivity losses.

What are the typical applications of vibration sensors

As we all know, process monitoring and state-based predictive maintenance are effective methods to avoid productivity loss, but the complexity of this method is comparable to its value. Existing methods have limitations, especially when they involve the analysis of vibration data (no matter how they are obtained) and the determination of error sources.

What are the typical applications of vibration sensors

Typical data acquisition methods include simple piezoelectric sensors installed on the machine and hand-held data acquisition tools. These methods have many limitations, especially compared with the ideal solution of comprehensive detection and analysis system, the latter can be embedded in the machine or machine, and can work autonomously. These limitations and their comparison with the ideal solution, autonomous wireless embedded sensors, are discussed in depth below. Optional analysis of complex system objectives for fully embedded autonomous detection elements can be divided into ten different aspects, including achieving high repeatability measurement, accurately evaluating collected data, and appropriateness.
