Description
This sensor, on battery (autonomy: 2 years), allows monitoring of vibrations 24 hours a day. The sensor is based on a 3-axis accelerometer and also has a temperature sensor.
This vibration sensor measures the following parameters:
- RMS Velocity: RMS Velocity (Root Mean Square) is the measurement of the average vibration speed over a time interval.It is often used to assess rotational vibrations and imbalances
- Acceleration (RMS & peak): The RMS acceleration is the root mean square value of the vibrational acceleration, while the peak acceleration is the maximum value reached by the vibrational acceleration. These measurements are important for assessing vibration intensity and potential for damage.
- Displacement: Displacement measures the total distance traveled by a vibrating part of the machine. It is a direct indicator of the magnitude of low frequency vibrations.
- Kurtosis: Kurtosis is a statistical measure that describes the “pointedness” or concentration of values in a distribution. A high kurtosis indicates a concentration of data around the mean, often a sign of shocks or transient faults in the vibrations.
- Crest factor: The crest factor is the ratio between the peak value and the RMS value of the acceleration. It helps identify shock events or intermittent faults that are not evident with just the RMS value
- Skewness: Skewness measures the degree of asymmetry of a distribution around its mean. Positive or negative asymmetry may indicate an abnormal condition in machine operation.
- Standard deviation: The standard deviation is a measure of the dispersion of vibration values around the mean. A high standard deviation can indicate high variability in vibration, which may be a sign of mechanical problems
This sensor is integrated into the IOT Factory platform:
