PCE-VT 3900 Vibration Analyzer

The PCE-VT 3900 is an excellent measuring tool for immediate and specific checking of vibrating parts, machines, and systems. This vibration meter makes use of the external vibration sensor to decide the vibration displacement (measuring variety 0.000 … 3. 9 mm), the vibration velocity (measuring variety 0.00 … 399.9 mm/s), and the vibration acceleration (measuring variety 0.0 … 399.9 m/s²).

Various measurement parameters are available for the vibration meter, which include RMS, peak, peak-top, and crest factor. The PCE-VT 3900 is equipped with a style that lets in a size to be automatically evaluated according to the limit values ​​of ISO 10816-3. The Vibration Meter PCE-VT 3900 analyzes the measured values ​​and shows a corresponding good/bad rating on the display. The built-in battery in the vibration measuring device has a capacity of 2500 mAh and can be recharged directly through the built-in micro-USB interface.

In addition to the normal measuring mode, the PCE-VT 3900 vibration analyzer has an FFT mode. In the FFT mode, the frequency spectrum for the measured vibration speed or vibration acceleration is calculated and displayed. The calculated FFT lines are displayed in a graphic representation in an overall view for the entire frequency band and parallel to this in a zoomed view to display the individual lines.

An additional function is route measurement. The route measurement is specially designed for recurring measurements at identical measuring points. This enables an orderly measurement of different measuring points. Because of its extensive measuring functions, the PCE-VT 3900 is therefore used for maintenance and repair work on machines.

The measurement data displayed for the diverse measurement features may be saved in the inner memory of the PCE-VT 3900. After a measurement, the measurement facts saved at the vibration meter may be transferred to a PC thru the integrated micro USB interface. The software program for the vibration meter then enables an image and tabular analysis of the measured values. The software program can export the measurement facts as a CSV report for similar processing. In order to keep the vibration measuring device as much as date, the software can also perform an automatic firmware update in addition to analyzing the measurement data.
