Control unit for a process system, process system and method for monitoring a process system

摘要

The invention relates to a control unit (12) for a process system (10), in which at least one medium (24) is transferred from at least one first state (26) into at least one second state (28). It is provided that by a controller with at least one measuring device (30, 31, 32) for detecting at least one measured variable of the medium (24) in the first state (26) and at least one measuring device (34, 36) for detecting at least one The controller is further connected to at least one measuring device (46) for detecting an energy consumption of the process system (10) during the transfer of the medium (24) from the at least one first state (26 ) is connected to the at least one second state (28), the controller comprises a processor (14) which sets the energy consumption in relation to the difference of the measured quantities of the medium (24) in the first state (26) to the second state (28), the controller includes storage means (16) defining an idealized theoretical energy demand for transferring a defined amount of media (24) from a defined first state to one In the second state, the controller includes a comparator (18) that compares the theoretical energy demand with the measured energy consumption relative to the actual amount of the medium, the controller including a display (20) that displays the result of the comparison.
