6.5 Calibration
Calibration is carried out separately for moisture and density. However, the procedure is the
same.
Prerequisites:
You are logged in with at least level 3 user rights (
You have created the product (
The system is ready to take measurements (sensor connected).
Samples of the product in the condition in which they are to be measured are available.
Distinguishing between measurement methods
There are the following different types of measurement or calibration, depending on the type of
application:
Laboratory measurement
– Single measurement, e.g. cigarette. One measured value is determined for the calibration.
– Multiple measurement procedure, e.g. for bulk goods in graduated containers.
Several measured values are determined; the graduated container must be rotated between
measurements.
Process measurement during a production process.
Several measured values, for which the corresponding samples of the product must be taken, are
recorded at certain intervals (we recommend taking at least 6 measurements).
– Continuous (online) measurement, e.g. for bulk goods that pass by the sensor on a belt conveyor.
– Bypass measurement, in which defined sample quantities to be measured are diverted from the
main flow and sent to the sensor at regular intervals. After the measurement, the sample is auto-
matically fed back into the main flow and the sensor is cleaned.
