Description
The Datastick VSA-1214 Vibration Spectrum Analyzer is Datastick's low-cost tool for vibration analysis and data collection. Paired with the Palm® TX handheld computer, it offers large storage capacity and security, long battery life, large display, and very good performance.
The VSA-1214 hardware module attaches to a high-performance Palm TX handheld computer and has a standard BNC connector and low-noise input that accommodates and powers almost any ICP®-type piezoelectric accelerometer. The VSA-1214 includes Datastick Spectrum handheld software and Datastick Reporting System™ PC software.
The VSA-1214 records and displays vibration FFT spectra in acceleration, velocity, and displacement, as well as acceleration waveforms. It also records and displays overall vibration with color-coded ISO (or custom) alert levels. For a full description of the display capabilities, see the description of Datastick Spectrum handheld software.
More Power
The VSA-1214 hardware module contains its own rechargeable Li-ion battery, which in normal use will last up to twice as long as the VSA-1212 on a single charge. An optional 5200 mAh rechargeable external battery pack is available if you need more power, and it gives you the added benefit of powering BOTH the VSA-1214 module and the Palm TX handheld computer.
Low Noise
A highly optimized design allows the VSA-1214 to find low-level, low-frequency peaks that can't be seen on equipment that costs three or four times as much. For more information, please see the full description of the VSA-1214 module.
Sharp Color Display and Secure Storage
The Palm TX has a unique rotating display which allows you to to view data in either vertical (portrait) or horizontal (landscape) orientations on its bright, razor-sharp 480 x 320 pixel screen. The Palm TX also features 100 MB of nonvolatile memory which keeps your data safe even if the battery drains all the way (which is highly unlikely, due to its efficient power management).
Virtually Unlimited Storage
The VSA-1214 provides virtually unlimited, extremely secure storage capacity. In addition to the Palm TX handheld's 100 MB of nonvolatile memory — which will hold approximately 3000 spectra or waveforms — the VSA-1214 also lets you record data directly to a Secure Digital (SD) memory card, which you can insert into the handheld computer. The VSA-1214 supports SD cards of up to 2 GB capacity, and you can use as many cards as you like — you'll never run out of space.
At the end of the day, simply insert the SD card into a card reader on your PC to export the handheld data to your PC, or you can use the Palm handheld's HotSync® feature single to export data to your PC with a touch of a button. With another couple of mouse-clicks, your data is imported into 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 an excellent vibration analyzer / data collector for route-based inspections, troubleshooting, and field service.
The VSA-1214’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.
Rugged Enclosure Option
For added protection from rough handling and the environment, the optional RC-4 Rugged Enclosure provides a splash-resistant, dustproof, impact-resistant shell that still allows access to the touch-screen controls for full operation.
