Thesis deals with the design, implementation and verification of functionality of station designed for measuring of acoustic emissions from pneumatic cylinders for the purpose of fault diagnosis. The first part of this thesis includes an overview of previous work dealing with the diagnosis of pneumatic systems, also works dealing with the diagnosis of various machine parts using acoustic emission. Further work contains a description of the proposed conceptual design and final draft is described in detail, including occurred complications and their solutions. The last part describes the results of measurements of acoustic emissions from damaged and undamaged cylinders. Functionality of the station is verified by comparing the frequency spectra and envelopes of measured acoustic emission signal.
