TIPS TO ENSURE YOU’RE GETTING ACCURATE & CONSISTENT DATA COLLECTION
When it comes to collecting vibration data, there are many variables that need to be taken into account in order to gain the valuable insights that vibration analysis can provide. If you miss a few key components when collecting data, it could render the data useless. We go over the 5 most common mistakes that we often see in the industry when it comes to collecting vibration data.
#1 Inconsistent Sensor Placement
Consistency is key! Placing the sensor in different locations each time can lead to inaccurate comparisons and misleading data. Always mount the sensor at the same point and orientation to ensure consistent readings.
#2 Improper Sensor Mounting
Loose or poorly mounted sensors can result in noise and inaccurate data. Ensure the sensor is tightly secured to the machine, ideally using a stud mount or magnetic base, depending on your equipment.
#3 Skipping Calibration Checks
Sensor calibration drift can happen over time, leading to incorrect data. Make sure you regularly check and calibrate your equipment to avoid collecting faulty data that could lead to wrong conclusions
#4 Ignoring Environmental Factors
Temperature, humidity, and external vibrations from nearby machinery can skew vibration data. Take steps to mitigate these influences or record them in your data notes to account for environmental variables
#5 Inadequate Sampling Rate
If your sampling rate is too low, you might miss critical frequency components. Ensure your data collection system is set to a rate high enough to capture the full spectrum of potential faults, particularly for high-speed machinery.
By avoiding these common pitfalls, you’ll be able to collect more accurate and meaningful vibration data, leading to better maintenance decisions and longer equipment life.
