Vibration Monitoring

The Vibration Monitoring app demonstrates how engines, electric motors and the like are monitored to detect
potential problems by their mechanical vibrations.
The sensor used is the
of 6666 Hz, to reach the highest level of bandwidth and best performance.
The app can compare two mechanical vibration data patterns, the vibration under test (Compare-app) with the
vibration of a standard scenario previously acquired (Training-app).
• Vibration Monitor - Training: is designed to acquire the vibration pattern of new or correctly functioning
equipment. The vibration pattern is converted using the Fast Fourier Transform (FFT) function and is stored
in the memory card on the
• Vibration Monitor - Compare: is designed to monitor the same equipment and compare the vibration
patterns with the original sample captured by Vibration Monitor - Training.
If the difference between the vibration analysis in Vibration Monitor - Training and Vibration Monitor - Compare
exceeds a set delta parameter (which can be modified according to equipment age and load conditions), the
green user LED on the
The Vibration Monitoring apps work with the following ST high accuracy motion sensor and operating parameter
settings:
• APP DATA INPUT: accelerometer values for training and compare phases
• SENSORS USED:
