Parameters
—
Dependent parameter
Resistance in ohms at -20...+120 °C
Options:
A resistance characteristic can be entered via these 8 parameters. Please refer to the sensor
manufacturer's technical documentation for this data.
7.11.1.4.1.3 —
Dependent parameter
Filter
Options:
This parameter sets a filter (floating mean value filter). This can be used to set the output value as a mean
value using three different options.
•
Inactive: Filter is not active
•
Low: floating mean value over 30 seconds
•
Medium: floating mean value over 60 seconds
•
High: floating mean value over 120 seconds
Using the filter "smooths" the output via the mean value so that it is available for further processing.
The filter therefore has immediate effects on thresholds and calculation values. The higher the degree
of filtering, the smoother the result. This means that changes to the output value become slower.
Example: On an erratic change in the sensor signal on the Medium setting, it will take 30 seconds for the
output value to propagate.
