Compact measurement system for calibration of vibration sensors
Šiket, Peter ; Beneš, Petr (oponent) ; Havránek, Zdeněk (vedoucí práce)
The objective of this thesis is to design and implement a compact measurement system that would be used for secondary calibration of vibration sensors. Hardware and software of National Instruments was used for development and implementation of the system. NI cDAQ 1974 chassis with analog output card NI 9260 and analog input cards NI 9250 is connected to the PC via USB interface. Graphical user interface allows user to create a calibration specification and run the calibration automatically. Calibration certificate is generated after the calibration run. It includes information about the sensitivity of the device under test, extended uncertainty of the measurement, phase shift and values of total harmonic distortion. The theoretical part contains information about technical requirements for such a calibration system based on norm ISO 16063-21. It also sums up theoretical and practical issues of design of a known calibration system of the company SPEKTRA Schwingungstechnik und Akustik GmbH Dresden, which is used for purposes of primary calibration. The practical part deals with design of the control system and graphical user interface. At the end, results of the secondary calibration are compared to the results of the primary calibration. The result of this thesis is the compact measurement system for secondary calibration of vibration sensors.
