Parameters in the Measurement
Mode CA, CF, CC, CH and CK
Function
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.
Invalid Measure Count
Standard Setting: 2 values
Setting Range: 0…10
Unit: Measurement Values
with 3
single values per second.
CA/CF/CK:
inactive
CC/CH:
Number of discarded (poor) measurement values after the
start of a new batch, when „No-Material-Delay“ has triggered. The first
measurement values will be rejected, e.g. due to dripping water.
Moisture Std. Deviation Count
Standard Setting: 5 values
Setting Range: 0…20
Unit: Measurement Values
with 3
single values per second.
CA/CC/CF/CH/CK:
If the parameters Temperature or EC-TRIME (RbC) are
not needed, the analogue output 2 can be setted tot he mode Moist/Moist
Std. Deviation. In this mode the standard deviation of all single moisture
values can be outputted. With this function the homogeneity of the sin-
gle measurement values can be determined and it is possible to control a
regulating process, e.g. pressure regulation.
Quick und Quick-Precision
With Meas Time (no. values)
Unit: without unit!
See in chapter
„Software tool SONO-CONFIG“
under point „Setting the precision
of a single value measurement”.
CA/CC/CF/CH/CK/CS:
Recommended is Quick Precision with Meas Time
= 2 where the TDR pulse is detected precisely. For still a little better
accuracies, Meas Time can be increased, however the single measurement
cycle is increased by 60 milliseconds per step (e.g. from 280ms to 340ms).
Older SONO probe versions do not have this Quick Precision function!
5.13 Operation Mode CA and CF at non-continuous Material Flow
For mode CA and CF the TRIME-GW Line are supplied with suited parameters for the averaging time.
The setting options and special functions of TRIME-GW Line depicted in this chapter are only rarely required.
It is necessary to take into consideration that the modification of the settings or the realisation of these special
functions may lead to faulty operation of the probe!
