SKU : VMA-503

I. BASICS OF VIBRATION
 What is vibration — What causes vibration
 Characteristics of vibration

Frequency — Displacement — Velocity —
Acceleration — Phase — Acoustical emission
Other Characteristics
Forced vibration, Free vibration, Natural
frequency, Resonant frequency, Critical speed
Measurement units
Peak-to-peak — in/sec peak — RMS
Conversion of vibration measurements
 Significance of vibration characteristics
Information provided by vibration frequency
Information provided by vibration amplitude
When to use velocity measurement
When to use displacement measurement
When to use acceleration measurement
Information provided by phase
 Assessing vibration severity
How much vibration is too much
General vibration severity chart
Acoustical emission bearing failure chart
II. VIBRATION MEASUREMENT
 Seismic velocity pickups (moving coil)

Theory of operation — Characteristics —
Magnetic interference
 Accelerometers
 Non-contact (Proximity) transducers
Theory of operation — Installation
 Mounting of transducers
 Seismic velocity pickups and accelerometers

Stud mounted — Epoxy mounted — Handheld without a probe — Hand-held with a
probe — Magnetic holder — Vice-grip pliers
— Shaft stick
 Guidelines for transducer selection
Selecting transducers
Mechanical characteristic of the machine
