Ill. 7 Moving Average Filter - Baumer OM30 IO-Link Operating Manual

Baumer
Moving Average filter
This filter smoothes the signal course by calculating the average of a specified number of mea-
sured values in a string of numbers. Due to average calculation, a change in distance becomes
increasingly visible.
Ill. 7: Moving Average filter
1 Raw data
3 Data after filtering with Moving Average
and Moving Median
The higher the number of measured values per filter, the longer the response time of the sen-
sor. This means that a change in distance only becomes fully visible for the output after a delay.
Option 1: Select the required filter length from predefined filter lengths
The following selection options are available:
Value
Standard
High
Very High
Highest
INFO
When several sensors are calculated, for example, for thickness measurement, the Standard fil-
ter should always be chosen to obtain a raw measured value of both sensors for further calcula-
tions.
