Page 28: Take Sample
ACO AUTOMATION COMPONENTS PC-Software DMMS/DIGISYS Take sample To obtain a material-specific balance, it is necessary to take samples from the flowing material as the digits are being recorded. The weight moistures of the samples are determined in the laboratory by drying or via „Karl Fischer Titration“. -

4 points. This type is supported by all DMMS moisture sensors. The sample is only available for this curve type. - Page 30 ACO AUTOMATION COMPONENTS PC-Software DMMS/DIGISYS Curve, Type 2..10 Points Evaluation of the samples is resulted on graph paper or via a table calculation system (e.g.: MS EXCEL). 2 data points (straight) or several data points can then be entered.

ACO AUTOMATION COMPONENTS PC-Software DMMS/DIGISYS 8.12 Example - install a measuring channel Measuring problem Sand is batched onto a weigher belt via dual discharge. Both discharge points are completely open for coarse batching, in the subsequent fine batching phase the 2nd discharge point half closes and the 1st discharge posi- tion closes completely. - Page 33 ACO AUTOMATION COMPONENTS Calibration 14. Switch to " Take Sample" register card and click the "by Start" box to enter a tick symbol. The measured values of the next batching are re- corded. Simultaneously, take material samples from the discharge points and ascertain the moisture value in the laboratory.
