Vibration monitoring sensors are responsible for measuring oscillations in structures or machinery. Predictive maintenance is their work area that recognizes the devices as the core tools. The oscillation or shaking is the result of the back-and-forth movement in the machine. That activity is usually caused by mechanical forces.

Vibration Monitoring Sensors: The Details and the Work
The oscillation detectors catch the movement to identify something wrong in the system further. This is a sign of minor damage that could cause major damage. By paying attention to the oscillation, you can detect abnormalities like missing components, bearing wear, imbalance, and misalignment.
The early detection of the shaking activity helps to predict the reparation needed and also prevents serious damage. These oscillation detectors are attached to the core components like turbines, fans, pumps and motors.
The sign of abnormality is reflected by excessive shaking or oscillation. When it happens, the detectors quickly send warnings. Based on this warning, the maintenance can be done immediately, prevent bigger problem In the system. To accommodate any kind of need for detectors, these oscillation monitoring devices come in three types: displacement, velocity and accelerometer sensors. The displacement detector catches the surface migration or movement as the result of oscillation.
The velocity detectors detect and quantify the real speed of the oscillation. Accelerometers, as the detectors anyone is familiar with, deal with the velocity alteration. They assess the velocity alteration rate.
As we can see above the work principle of the sensors is simple. By catching the oscillation and then processing it. However, the algorithm from the detectors installed to the last assignment of the tools is quite long. The following are the steps of the detector work.
Picking the Suitable Sensor
The very first is knowing the necessity of the system and the compatible detector. Finally, choose the detector, the things to consider are the machinery type that you use, the environment around the machine, amplitude and the range of the frequency.
Mounting or Installation
The quality of the data can be affected by how well the tools are mounted. It doesn’t seem important but otherwise, the wrong installation could disturb the result.
Data Collecting
After the devices are attached well to the object, they can start to collect the data. To improve the quality of the data, some detectors use signal conditioning.
Signal Analyzing
In this stage, the signal is shifted from analogue to digital. The process includes filtering that separates the data core from the unwanted noise, and only takes the relevant one. This stage is considered to be a very crucial one because it determines the interpretation in the next stage.
Interpretation
In this phase, the data is interpreted to conclude the frequency pattern. The abnormal pattern then is detected to be an indication of misbehaving of the system.
Adjusting the Threshold
After knowing the pattern and the normal oscillation level, the users should adjust the threshold to identify the excessive activity.
Send the Notification
If the oscillation is beyond the limit, the alert system sends a notification in the form of an alarm and report. It doesn’t just send the emergency notification but also reports the data. The decision maker could use the data to decide what to do or what maintenance should they do.
Monitor the Rest of the Process
After the problem is solved, continue the monitoring activity. Although one of the problems is found and solved, it is not impossible for it to happen again. During the system recovery, the experts are expected to improve. However, an error could happen even after the improvement so the monitoring should be continued.
The Industrial Application of Vibration Monitoring Sensors
The devices can support several industries in supervising the oscillation to level up the business.
High Technology
AI systems And IoT are integrated with the oscillation detector. The network connection is to reach data transfer high speed and accurate real-time data download.
Asset Management
The repair schedule can be boosted to be more efficient and effective, eliminating unnecessary excessive schedules. Related to the cost, it helps to cut off the bill.
Manufacturing
The oscillation supervising on heavy machines is necessary to avoid production failure.
Transportation
Aviation and railways use the oscillation detector to identify abnormal activities.
Those are four major industries that employ the sensors. The other sectors are safety and risk management, energy sector, predictive maintenance and other industries that run machines that might vibrate.
