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:

■

Note: Details about the data filters can be found in the "Ethernet Communication

Protocol" manual at www.pepperl-fuchs.com.

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.
