riven by increased automation, demand is
rising for high-volume, smaller systems—
such as machine spindles, conveyor belts,
sorting tables, or machine tools—that require better
predictive maintenance.
Machine downtime in these applications is a critical
consideration in terms of customer experience
and profitability. In the past, accelerometers were
primarily used for condition monitoring of heavy,
high-end machinery such as windmills, industrial
pumps, compressors, and HVAC systems.
This white paper will compare different
accelerometer technologies in industrial condition
monitoring.
Critical Factors
For industrial condition monitoring and predictive
maintenance applications, the following vibration
specification parameters are considered critical
to ensure long-term, reliable, stable, and accurate
performance:
• Wide frequency response
• Measurement resolution and dynamic range
• Long-term stability with minimum drift
• Operating temperature range
Wide Frequency Response
In order to detect all possible failure modes
of machinery, the frequency response of the
accelerometer should be 40 to 50 times the shaft
