Tab.1.4: Important terms
Response time
(Response time)
Also integration time or measurement time. Maximum length of time from
the occurrence of an erratic change in distance to the steady state of the
measurement value.
The response time depends on the set average calculation. Although the
average calculation increases the response time, it also improves repro-
ducibility.
Resolution Smallest representable change in measurement value, distance and
speed.
Warmup time Time the sensor needs in order to reach the operating temperature. An op-
timal measurement is only possible after the end of the warmup time.
The warmup time is approximately 20minutes.
Output resolution The output resolution describes how the measurement values are pre-
sented on the display and digital interfaces.
Depending on the device model, the output resolution of the ODS9 is
0.01mm or 0.1mm and cannot be changed.
Output time
(Output time)
Time interval of measurement value updating at the interface.
Readiness delay The delay before start-up indicates the point in time when the first valid
measurement can be obtained after switching on.
Data storage
IO-Link data storage
Data memory of the connected IO-Link master.
DSUpload Data Storage Upload.
Upload to the data memory of the connected IO-Link master.
Accuracy Maximum expected deviation of the measurement value between the de-
termined and real distance value within the specified measurement range.

Light switching
Dark switching
The behavior of the switching output if an object is within the taught/config-
ured switching distance.
• Light switching: switching output active (high)
• Dark switching: switching output not active (low)
Diffuse reflection Return and/or degree of reflection of the radiated light. Observe the specifi-
cations regarding diffuse reflection (see chapter 12 "Technical data").
• 90% is white
• 6% is black
Reproducibility Also repeatability. Deviation of multiple measurement results relative to
each other under identical conditions. Dependent on the measurement dis-
tance and the diffuse reflection of the measurement object.
The reproducibility can be considered as the measure of measurement
value noise and is affected by the configuration of the response time.
Triangulation measurement
principle
Distance measuring procedure, which determines the distance of an object
by the incidence angle of the light reflected from the object.

Device description
Leuze electronic ODS 9 20
Measurement value processing and filtering is set according to the given requirements and the application
via the display or using the SensorStudio configuration software.
By changing the measurement value processing or filtering, the response time and accuracy can be in-
creased.
NOTICE
A higher response time presupposes the possibility of measuring an object for a longer period.

Filter
Filter settings > Filter type > Averaging/outlier suppression
A floating average value is calculated over the number of set measurement values.
The measurement value noise decreases, i.e., measurement value fluctuations become smaller.
If the measurement value changes erratically, the output value moves linearly from the old measurement
value to the new measurement value over n measurements.
The higher the number of measurements is set, the higher the response time of the sensor. With dynamic
applications, averaging should be set to a very low number of measurement values or switched off alto-
gether.
The time of measurement value updating is not affected by the filtering.
Outlier suppression
Filter settings > Degree of suppression > Coarse/Medium/Strong
Measurement results with excessively high or low measurement values (referred to as "outliers" or
"spikes") are suppressed or rejected according to the set filter depth.
• The user sets the number of measurements via the display or using the configuration software Sen-
sorStudio .
• The sensor performs the set number of measurements on the object, e.g. 100measurements.
Due to physical reasons, the measurement results are not all the same. The measurement values have a
scatter which corresponds to a normal distribution comprising a large number of similar measurement val-
ues and a small number of excessively high or low measurement values (outliers, spikes).
