PCE Vibration meter PCE-VT 3950

The vibration measuring device is an ideal measuring tool for quick and precise testing of vibrating parts, machines and systems. This vibration measuring device uses the external vibration sensor to determine the vibration displacement (measuring range 0.000 ... 3.9 mm), the vibration velocity (measuring range 0.00 ... 399.9 mm/s) and the vibration acceleration (measuring range 0.0 ... 399.9 m/s²). Various measurement parameters are available for the vibration meter, such as RMS, peak, peak-to-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 analyses the measured values and shows a corresponding pass/fail evaluation on the display. The built-in battery of the vibration meter has a capacity of 2500 mAh and can be recharged directly via the built-in micro-USB interface.

In addition to the normal measurement mode, the vibration meter also has an FFT mode. In FFT mode, the frequency spectrum for the measured vibration velocity or vibration acceleration is calculated and displayed. In a graphical display, the calculated FFT lines are shown in an overall view for the complete frequency band and in parallel in a zoom view to visualise the individual lines.

An additional function is route measurement. Route measurement is specially designed for recurring measurements at identical measuring points. This enables an organised measurement of different measuring points. The vibration measuring device is therefore used for maintenance and repair work on machines due to its extensive measuring functions.

The internal memory of the vibration measuring device can be used to save the displayed measurement data of the various measurement functions. After a measurement, the measurement data stored on the vibration analyser can be transferred to a PC via the built-in micro-USB interface. The software for the vibration measuring device then enables the measured values to be analysed graphically and in tabular form. The measurement data can be exported as a CSV file via the software for further processing. To ensure that the vibration measuring device is always up to date, the software can also be used to analyse the measurement data and perform an automatic firmware update.
