Vibration spectrum analyzer uses piezoelectric accelerometers



VSA-1212 module from Datastick Systems is said to be the first PDA-based vibration spectrum analyzer to use standard, off-the-shelf ICP-type piezoelectric accelerometers for machine diagnostics.

PDA-based vibration spectrum analyzer from Datastick Systems is said to be the first to use standard, off-the-shelf ICP-type piezoelectric accelerometers for machine diagnostics, predictive maintenance, and routine troubleshooting.
System includes the VSA-1212 analyzer module that attaches to select PDAs running Palm OS; new Datastick Spectrum handheld software that collects vibration measurements and displays them in time waveforms and FFT spectra with alarm levels; and Datastick Reporting Systems (DRS) software that receives data from the handheld into a special VSA Microsoft Excel workbook on the PC. Data are collected, viewed, analyzed, and stored on the PDA, then exported to a desktop PC for further analysis, trending, reporting, storage, and publishing to the enterprise and the Web. When combined with an off-the-shelf ICP-type accelerometer, Palm Powered PDA, and Microsoft Excel software, the VSA-1212 becomes a complete hardware and software system for vibration analysis.

Main display provides relevant information in one view. Cursor-position readouts show specific values when a user touches a point with the handheld's stylus. Reloadable configurations allow input and display parameters to be changed quickly. VSA-1212 supports following handheld devices: Palm Tungsten T, T2, T3, C, Palm m-500 Series, Garmin iQue 3200, and Garmin iQue 3600.
