Použití tlakového relé v pneumatických systémech

Abstract

This bachelor thesis deals with description of a pressure relay and its use in pneumatic systems. Introductory part contains of a theoretical description of pneumatic valves, electrical relay and pressure relay. Secondly, there is information about various types of pressure relays from different manufacturers and a description of similarly working pressure switch. In the following part of the thesis pneumatic systems that use pressure relays for their functioning are designed and described. Three of them are then tested in Pneutrainer by SMC. Finally, there are a few practical examples of pressure relay’s use.
