Definitions
- the oil-cellulose system behaves itself here, as if it consists from the oil only : the temperature change is so fast, that the water from the oil filling doesn't have enough time to migrate back to the cellulose, or to diffuse back to the oil..
- the first data line 41 connects the control port 42 with the process control device 4
- the second data line 43 connects process control device 4 with the remote PC (not shown)
- the third data line 46 connects the process control device 4 with the temperature governor 6 .
- the process control device 4 evalutes the Ud,t-processing as correct and relevant for the elapsed time-period and for another pre-defined time period in future and subsequently calculates and/or changes of value of the setting point (Tsoll-value) and send this value via third data line 46 to the temperature governor 6 .
