Device

The vibration meters PCE-VT 3800 and PCE-VT 3900 are capable of measuring and monitoring
vibration in machine components. The measuring units include vibration acceleration, vibration
velocity and vibration displacement. The reading for the set measuring unit can be shown as
RMS, peak, peak-peak value or crest factor. These measured values can be used, for instance,
to detect machine imbalances and arising bearing damage.
Apart from a Hold function which freezes the current measurement value, the device also has a
function to show the maximum value. During a measurement, this function displays the highest
value measured so far in addition to the current measurement value.
Another feature is the automatic evaluation of the measurement value with regards to the ISO
standard 10816-3. When this feature is enabled, the current measurement value is classified into
one of four defined zones in line with the corresponding limit values and highlighted by a colour.
Other features of the PCE-VT 3800 include a memory for manual measurements and a data
logger function for recording measured values over a longer period of time. In addition to the
features described above, the PCE-VT 3900 offers functions for route measurement, calculation
of FFT and RPM measurement.
With the PC software included in the scope of delivery, the saved data can be imported from the
meter and displayed, evaluated and archived accordingly.
The meters have an internal LiPo battery that is charged via the USB socket with a common USB
mains adaptor and the battery life is approx.15 ... 20 hours, depending on the set brightness.
