Processing of invalid measured values

The Processing of invalid measured values function defines the behavior of the sensor when

the sensor records an invalid measured value. This function can be used, for example, to mask

recurring reflections of machine parts or reflections of measurement objects in a dynamic appli-

cation. Invalid measured values occur when

there are no objects in the measurement range (MR) or

the signal is too weak due to reflections or unidentifiable objects.

The function can be configured via the following parameters:

Specify the status of the analog output in case of invalid measured values. Possible options:

▪ The analog output holds the last valid measured value.

▪ The analog output holds the min. output point.

▪ The analog output holds the max. output point.

Time period (Hold Time) during which an invalid measured value should be suppressed.

The time period is used to mask invalid measured values at the outputs. The output (digital

or analog output) is set only after expiration of the time period.

Processing of invalid measured values – example 1

Parameters:

▪ Type of processing of invalid measured values: min. output point

▪ Time period (Hold Time): 1000 ms

Interpretation: Invalid measured values are ignored at both the digital and analog output.

The last valid value is maintained during the time period. The type of processing of invalid

measured values has no effect yet at this point.
