PdM Program
AIR-SEPARATION FACILITIES USE a wide variety of rotating and reciprocating machinery. Predictive maintenance for this equipment involves monthly
monitoring at hundreds of measurement points
within a plant. The resulting vibration data, including
high-frequency measurements in the 20-kHz range,
provides valuable indications of machinery health.
For vibration analysts at a manufacturer of industrial
gases, however, the data-collection process presented
a dilemma.

NOVEMBER 2017

Manufacturer of industrial gases found
'quick' relief for an unusually tough
vibration-monitoring challenge.

The analysts had concluded that a comprehensive,
accelerometer-based predictive-maintenance (PdM)
program linking a network of plants across the country would be ideal for their company-except for the
problem of mounting requirements for high-frequency measurements.
Conventional wisdom held that accelerometers
needed to be stud-mounted to provide accurate
readings at high frequencies. For the analysts,
stud-mounting an accelerometer at hundreds of mea-

Vibration data, including
high-frequency measurements in the 20-kHz
range, provides valuable
indications of machinery
health. The challenge
for vibration analysts
dealing with multiple
air-separation facilities
and countless rotating- and reciprocating-equipment systems
is how to efficiently
collect and process it.
