Add Vibration to Analysis Mix

Vibration
analysis can play a key role in a predictive maintenance program, but
several obstacles have prevented wide spread use. The PDA based
VSA-1214 and VSA-1215 Vibration Spectrum Analyzers may change this
common situation. “Starting with price, going on to ease of use, and
finally to the big hurdle of lack of in-house vibration expertise in
many facilities, our entry-level VSA-1214 lets users perform vibration
analysis for machine-condition monitoring, predictive maintenance, and
routine troubleshooting, reducing costs and downtime,” noted Michael
Scandling, vice president of Marketing, Datastick Systems Inc.
Operational
training is easy and customers won’t need in-house vibration analysts
because the open PC software is based on Excel. Engineers can email
their data to the consultant of their choice. Pocket-sized, these
devices include the Spectrum version 1.6 software for collecting
vibration measurements as well as displaying and storing them as time
waveforms and FFT spectra.
The VSA-1215 system displays and
records overall vibration and ISO vibration severity alerts, as well as
acceleration waveforms with a resolution of up to 6,400 points (3,200
points for the VSA-1214); and acceleration, velocity, or displacement
spectra with up to 3,200 lines of FFT resolution (1,600 FFT lines for
the VSA-1214). User-selectable maximum frequencies range from 20 KHz
down to 50 Hz (10 KHz to 50 Hz for the VSA-1214). The tenth-order
hardware anti-aliasing filter gives a clean signal, while low-noise
electronics and specialized algorithms keep the noise floor so low that
velocity signals are useable down to 1 Hz (60 CPM - cyces per minute).
