Mode CS:
(Cyclic-Successive) For very short measuring processes (e.g. 5…20 seconds) without floating average,
with internal up to 100 measurements per second and a cycle time of around 200 milliseconds at the analogue
output. Measurement mode CS can also be used for getting raw data from the TRIME-GW Line without averaging
and filtering.
Mode CA:
(Cyclic-Average-Filter) For relative short measuring processes with continual average value, filtering
and an accuracy of up to 0.1%
Mode CF:
(Cyclic-Float-Average) for continual average value with filtering and an accuracy of up to 0.1% for very
slow measuring processes, e.g. in fluidized bed dryers, conveyor belts, etc.
Mode CK:
(Cyclic-Kalman-Filter) Standard setting for SONO-MIX probes for use in fresh concrete mixer with
continual average value with special dynamic Kalman filtering and an accuracy of up to 0.1%.
Mode CC:
(Cyclic Cumulated) with automatic summation of a moisture quantity during one batch process.
•
Precision of a single TDR radar pulse measurement (see in chapter „Software tool SONO-CONFIG“ under point
„Setting the precision of a single value measurement”.
•
Calibration (if completely different materials are deployed)
Each of these settings will be preserved after shut down of the probe. All parameters are stored on a permanent
basis.
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 insuf-
ficient 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.
