As explained in
, the sensor can average the spectra of several data
blocks recorded in succession, and continue to process this averaged spectrum (to
output the spectrum or to detect the peaks in the spectrum). Averaging improves the
signal-to-noise ratio in the spectrum, but the output data is updated correspondingly
less frequently.

Temperature monitoring (Index 4352-4355)
Temperature changes in the application are measured via the back of the sensor hous‐
ing. The better the thermal diffusivity of the material on which the sensor is mounted,
the more accurate the measurement.
If the sensor is non-flush or there is an adapter plate with poor temperature conductiv‐
ity between the sensor and the machine, the influence of the self-heating of the sensor
is stronger and the measured value is less accurate. Observe
here.

Shock (Index 4434–4448)
In addition to the vibration sensor for vibration, there is another MEMS-based vibration
sensor for shock detection in the Multi Physics Box.
With a measuring range of up to 200 g, the maximum accelerations are measured in all
three axes, thus monitoring shock events.
