Description
Summary:In line with technological sensor developments, the possibility of making online qualitycontrols or fluid processes also increases. Two of these controls have beeninvestigated in this project, namely measurement of oxygen in liquid as well as controlof conductivity after completion of the clean in place. The issues are "what sensorsand opportunities are available in the market to enable automation of thesecontrols?", and "how can sensors be implemented in the production process and whatprofits can be made?"The aim of the thesis work is to present what possibilities and limitations there arefor the purchase of sensors in order to enable automation of the measurementsmentioned in the problem description, as well as to suggest sensors and to developlayout proposals in order to describe where in the process the controls are to beimplemented and what impact they have.Several sensors were found, and two of these are considered best suited forintroducing at the factory in the field of pharmaceutical production where the thesishas been carried out. Considering the time aspect and the complexity involved inmanufacturing, the work has been limited due to an implementation is notconceivable.A process flow analysis, literature studies, interviews and a selection have resulted ina situation assessment, market research and a layout proposals. This has then beenanalyzed and the different solutions have been ranked, mapping of profits andproposals for working methods for implementation.Finally, the conclusion was that the two selected sensors are possible to beimplement. Automating these controls involves a number of benefits such asimproved work environment, reduced waste and financial gains. The implementationshould not adversely affect the process, and it would be an appropriate step towardsfurther digitization and Industry 4.0.
