The PCE-VT 3900S is a vibration meter ideal for fast and precise measurement of vibrating parts, machines and systems. This vibration meter uses the external vibration sensor to determine the vibration displacement, the vibration velocity, and the vibration acceleration. Included with this version is a measurement sensor tip for hard to access measurement locations. Various measurement parameters are available for the vibration meter, such as RMS, peak, peak-peak and crest factor. The vibration meter is equipped with a mode that allows a measurement to be automatically evaluated according to the limit values ​​of ISO 10816-3. The vibration meter analyzes the measured values ​​and shows a corresponding good/bad rating on the display. The built-in battery in the vibration meter has a capacity of 2500 mAh and can be recharged directly via the built-in micro-USB interface.

Included with the PCE-VT 3900S, are the PCE-VT 3xxS sensor with handgrip and PCE-VT-NP. Hard to access measurement locations can be reached with the measuring tip. The tip should be placed as vertically as possible on the measurement surface in order to achieve accurate measurements. 

In addition to the normal measuring mode, the vibration meter 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 in a zoom 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 ideal for maintenance and repair work on machines.

FFT Acceleration: 10 Hz – 8 kHz

FFT Velocity: 10 Hz – 1 kHz

Number of FFT lines: 2048

Route Measurement: 100 routes each with 100 machines each with 100 measuring points with 1000 measured values each 

The measurement data displayed for the various measurement functions can be stored in the internal memory of the vibration meter. After a measurement, the measurement data stored on the vibration meter can be transferred to a PC via the built-in micro-USB interface. The software for the vibration meter then enables a graphic and tabular analysis of the measured values. The software can export the measurement data as a CSV file for further processing. In order to keep the vibration meter up to date, the software can also perform an automatic firmware update in addition to analyzing the measurement data.
