13.3 Operating range of the vibration monitoring unit
The operating range is independent from the measuring range. It can be derived from the
maximum acceleration, which is 16.5 g across all frequencies. The maximum measurable
vibration velocity is based on the formula
𝑣
𝑚𝑎𝑥
= ∫ 𝑎
𝑚𝑎𝑥
For sinusoidal vibration,
𝑣
𝑚𝑎𝑥
=
𝑎
𝑚𝑎𝑥
2𝜋𝑓
applies
Fig. 1: shows the operating range of the vibration monitoring unit, which is limited by the
maximum measurable vibration velocity in mm/s depending on the frequency in Hz.
