Frequency and acceleration limits
The measurement frequency range of the measurement chain has to be
determined electrically from the upper cut‐off frequency of the amplifier. You
can find the appropriate data in the operating manual for your amplifier.
Maximum permissible acceleration has a decisive effect on the mechanical
characteristics of the displacement transducer (see chapter 11 "Specifications",
page 21).
In the case of displacement probes, care must be taken that the probe pin does
not withdraw from the measurement object due to inertia.
To a first approximation, many tasks may generally be regarded as sinusoidal.
At maximum permitted acceleration a
