Following Bearing Damage Progression to Failure Mode
When vibration enveloping was introduced several decades ago, it became possible to detect damages in earlier stages than before, and it then became relevant to talk about realistic pre- warning times.

Sensor Reliability Impact on Predictive Maintenance Program Costs
Accelerometers with lower mean time between failures (MTBF) values result in higher costs for permanently installed vibration sensor applications - as much as $60 per vibration sensor. By taking the MTBF and manufacturing quality into account when making an accelerometer purchase, you can achieve lower overall program costs.

Exploring Vibration Analysis Technologies
In the realm of industrial maintenance, understanding the health of machinery is paramount. One of the most effective tools in this pursuit is Vibration Analysis technology. By examining the oscillations and vibrations of machinery, it’s possible to detect early signs of wear, misalignment, and other issues before they escalate into costly failures. In this article, we will delve into the different facets of Vibration Analysis technology and compare Handheld/Portable, Wireless, and Continuous Online Condition Monitoring solutions.
