Data Filter
The R2000 allows you to preprocess data. This can be useful for suppressing
measured value noise or reducing the volume of output data, for example. The
following measured data filters are available:
■
Average value filter:
All distance data and amplitude data is determined
arithmetically using an appropriate filter width.
■
Median filter:
A value (median) is determined using a selectable filter
width; half of the data is greater than or equal to this value.
■
Maximum filter:
Using a selectable filter width, the arithmetic mean is
determined for a subset of the data. Starting with the highest measured
value from the measurements within the filter width, the data is used that is
shorter than the maximum value by a selectable range or which has the
same measured value as the maximum value. Data outside of this range is
discarded.
■
Reflectivity filter:
Using a selectable filter width, the arithmetic mean is
determined for the data. The calculation only includes data with signal
amplitudes greater than or equal to an adjustable amplitude threshold.
Note: Details about the data filters can be found in the "Ethernet Communication
Protocol" manual at www.pepperl-fuchs.com.
