DataStick Vibration Spectrum Analyser

Datastick® VSA-1214/15

Vibration Spectrum Analyzer. Now anyone can afford an easy-to-use vibration analyzer / data collector for predictive maintenance / machine health monitoring and troubleshooting.

Introduction

Datastick takes PDA-based instrumentation to a new level with its NEW Vibration Spectrum Analyzer, the VSA-1214/15 module, which, when attached to a Palm handheld running Datastick Spectrum software, makes a complete handheld vibration analyzer for predictive maintenance, machine condition monitoring, troubleshooting, and field service.

Datastick Spectrum software software brings instrumentation on handhelds to a new level, by enabling sophisticated FFT displays with numerous windowing options and several tools for examining the data, including one for calculating differences in amplitude between frequencies. Spectrum includes Datastick Manager software, which manages files and permits moving between Datastick software applications without exiting the application you’re working in, as well as a number of other capabilities. It comes with Datastick Reporting System™ for VSA.

The VSA-1214/15 hardware module is part of the VSA-1214/15 Vibration Spectrum Analyzer system, which consists of the following components The VSA-1214/15 module, Datastick Spectrum software for Palm Powered® handheld computers (Included), Datastick Reporting System™ for VSA software for Windows® PCs (Included) A PalmPowered® handheld computer

Key Features

  • Uses standard ICP®-type piezoelectric accelerometers
  • Attaches to Palm Powered or Garmin iQue handheld computers
  • Includes Datastick Spectrum handheld software and Datastick Reporting System™ PC software for analysis and trending
  • Provides vibration waveforms and FFTs
  • Self-powered or optional external power
  • Lightweight

Description

The Datastick VSA-1214/15 module attaches securely to the back of a Palm Powered Tungsten T/X handheld computer. It is the hardware interface component of the Datastick VSA-1214/15 Vibration Spectrum Analyzer system, which also includes Datastick Spectrum handheld software and Datastick Reporting System PC software.

Up to 100 MB of recorded waveform and spectrum data (approximately 3000 captures) can be stored in the Palm T/X handheld computer. External 2-4 GB SD cards allow additional storage. With a single touch of a button and one mouse-click, data can be exported to Datastick Reporting System software on the PC for analysis, trending, reporting and archiving.

Compact size and the straightforward operation of the Datastick Spectrum software make the VSA-1214/15 an excellent vibration analyzer / data collector for route-based inspections, troubleshooting, and field service. The VSA-1214/15’s affordable price and ease of use make it possible for even the smallest facility to enjoy increased productivity resulting from monitoring and analyzing machine vibration in predictive maintenance.
