Parameters in the
Measurement Mode CA, CF,
CC, CH and CK
Function
Average-Time
Standard Setting:
2s
Setting Range: 1…20
Unit: Seconds
CA/CF:
Time (in seconds) for the generation of the average value
can be set with this parameter.
CC/CH/CK:
Setting of the time for calculation of the trend or
expectation value for the
Boost
&
Offset
function.
Filter-Upper-Limit-Offset
Standard Setting:
25%
Setting Range: 1….20
Unit: % Absolut
CA/CC/CF/CH/CK:
Too high measurement values generated due
to metal wipers or blades are filtered out. The offset value in % is
added to the dynamically calculated upper limit.
Filter-Lower-Limit-Offset
Standard Setting:
25%
Setting Range: 1.….20!
Unit: % Absolut
CA/CC/CF/CH/CK:
Too low measurement values generated due
to insufficient material at the probe head are filtered out. The
offset value in % is subtracted from the dynamically calculated
lower limit with the negative sign.
Upper-Limit-Keep-Time
Standard Setting:
10
Setting Range: 1...100
Unit: % Absolut
CA/CC/CF/CH/CK:
The maximum duration (in seconds) of the
filter function for Upper-Limit-failures (too high measurement
values) can be set with this parameter.
Lower-Limit-Keep-Time
Standard Setting:
10
Setting Range: 1...100s
Unit: Seconds
CA/CC/CF/CH/CK:
The maximum duration (in seconds) of the
filter function for Lower-Limit-failures (too low measurement
values) for longer-lasting "material gaps", ie the time where no
material is located on the probe´s surface can be bridged.
Moisture Threshold
(start threshold in %-moisture)
Standard Setting: 0.1%
Setting Range: 0
….100%
Unit: % Absolut
CA/CF/CK:
inactive
CC/CH:
The accumulation of moisture values starts above the
„Moisture Threshold“ and from here the analogue signal is
outputted. The accumulation pauses and will be frozen if the
moisture level is below the threshold value. The
No-Material-
Delay
time starts and material gaps (disturbance) can be
eliminated.
No-Material-Delay
(period time)
Standard Setting: 10s
Setting Range: 1….100s
Unit: Seconds
CA/CF/CK:
inactive
CC/CH:
The accumulation stopps if the moisture value is below
the
Moisture Threshold
. The accumulation pauses for the period
of the setted delay time and will be frozen if the moisture level is
below the threshold value. The SONO probes starts again in a
new batch with a new accumulation after the setted time span of
the “No-Material-Delay” is completely exceeded.
Boost
Standard Setting: 35nn
Setting Range: 1….100nn
Unit: without unit!
CA/CF:
inactive
CC/CH/CK:
Defines, how strong single measurement values are
weighted dependent on deviation to the current expected average
value. With e.g. Boost=35, a single measurement value is
weighted with only 65% (100-35) for a new average value.
Offset
Standard Setting: 0.5%
Setting Range: 0
….5%
Unit: % Absolut
CA/CF:
inactive
CC/CH/CK:
Non-linearities in the process can be compensated
by higher weighting of higher values. Can be used e.g. in fluid bed
dryers or under silo flaps where non-linearities can occur due to
changes in the material density during process. “Offset” works
together with the parameter “
Average-time
”.
Weight
Standard Setting: 5 values
Setting Range: 0
…..50
Unit: Measurement Values
CA/CF/CK:
inactive
CH:
Smoothing factor for analog output setting. This parameter
influences the reaction/response time with factor 3. E.g. 15 values
responds to a reaction time of 15/3=5 seconds.
CK:
The reaction/response time works nearly 1:1.
E.g. 15 values responds to a reaction time of 15 seconds.
