Anotation:
Subject is offered to PhD students and it is devoted to measuring technique in general, with emphases to advanced DAQ systems and their use in engineering. It includes strategy and design of the measurement. Study program of deals also with accuracy of the measurements and commonly used techniques for their result interpretation. Bases of transducers and the most frequently used sensors are described and their function is explained (namely temperature, pressure, flow and concentration measurements are discussed and demonstrated in details). Fundamental interfaces are investigated as well - RS232, GPIB, CANBUS, multiplexers, ELMB modules, typical measuring cards. The following software applications are available and included in curriculum : LabView, BridgeView, TestPoint, PVSS II.
Study targets:
Significantly extend theoretical and namely practical knowledge about contemporary methods of the engineering experiment in wide range of engineering applications.
