2.2.2 Measuring range limits
The measuring range can, according to the application, be adapted to the
machine or monitored plant by a wide range.
In the table below the measuring range limits (min. max.) are given
dependent upon the characteristic variable = effective (RMS) value of
vibration velocity.

For the selected measuring range, signals of 4 - 20 mA per sensor
proportional to the characteristic variable are available at the analogue
outputs.
2.2.3 Display value and bandwidth
Acquisition of the measured data is done by vibration acceleration sensors.

2.2.4 Signal detection
The output voltage of the measurement sensors is proportional to the
measured magnitude of the time signal (vibration acceleration).
The following signal detection step is carried out by the VIBROCONTROL
1500:
Calculation of the effective (RMS) value of vibration velocity from an
integration of the vibration acceleration signal.
