Patent ID: 10883951

Abstract:
Arrangement and method for detecting damage to an inner coating of a container is provided. The arrangement has been devised which is influenced by damage to the inner coating and/or actuation of plant parts (shut-off valves) and/or by electrical changes in the current paths. This is accomplished such that the latter generates a reproducible signal excursion which can be assigned to the respective activity and therefore to the corresponding parts of the plant, such as a container. Thus, by means of the measuring arrangement, both slowly changing values, which arise as a function of process-induced slowly changing process parameters, such as temperature, concentration, conductivity, and other gradually occurring damage to an inner coating, and also short-term significant changes of values are detected, which are brought about e.g. by pumping operations or by connecting together plant parts, which influence the electrical properties of the system. The detected signal excursion is interpreted.
