Vibration Analysis
Two Minute Tips
Key Features for a Vibration Analyst
For more complex analysis, analysts require more advanced tools to better diagnose issues. Playing the TWF as an audio file is a good way of listening to the vibration to potentially hear knocking, pinging or high frequency whistling, denoting a problem to further diagnose, as if you were actually beside the machine.

Maximum Cable Length for Vibration Sensors
A vibration sensor produces an AC voltage dependent on the vibration signal being measured. As such, it’s subject to all the limits of AC signals. Long cable runs are likely to introduce enough capacitance into the sensor circuit to cause distortion, which makes being able to calculate cable length limits very important..

GMF Calculation and Gearbox Problems Detection
Gearbox defects can be identified with a quite high accuracy using vibration analysis. This is because the fact the most common defect frequencies are the fundamental Gear Mesh Frequency (GMF) and its harmonics (such 2x GMF, 3x GMF) which can easily detected.

4-20 mA vs. IEPE Vibration Sensors for Process Control Systems
With process control systems, it’s simple (and smart) to incorporate vibration data into an existing monitoring program. Either loop-powered 4-20 mA sensors, which output a direct 4-20 mA signal, or IEPE sensors, which output dynamic data that can be converted into an acceptable process signal, can be used..
