Pneumatic components represent an important part of many technical devices in transportation, mechanical, automotive and power engineering etc. The proper function of these components decides not only on the correct function of production equipment, for example, but in many cases influences also the safety of passengers, operators etc. The diagnosis of these systems is currently based mainly on monitoring of vibrations, possibly also are verified devices on the principle of ultrasound. Possibilities of these methods have proven to be inadequate, less sensitive and largely unreliable. Another diagnostic procedure that is being tested is the noise analysis of activity of diagnosed devices. Also, this method proves to be unsuitable for practical use in operational diagnostics. However, the required new methods of increasing sensitivity speed and efficiency of NDT, their automation, minimizing the human factors and the reduction of operating costs. Ideally, it is the possible to consider a combination of acoustic emission with other methods, thereby ensuring high sensitivity reliability at the same time.
