Evaluation of pressure conditions in the quenching chamber of low-voltage device
Nevrzal, Filip ; Vávra, Daniel (referee) ; Valenta, Jiří (advisor)
In this master’s thesis there is firstly conducted research about pressure measurement. Next there is mathematical description of thermodynamic conditions in used testing chamber by using magnetohydrodynamic and Maxwell equations. Next chapter deals with testing chamber itself, more precisely with function, model and changes done to it. In practical part there are data measured by used sensors, which are also closer described in this chapter. In next chapter there is comparison of reaction times of used sensors and their frequency specters, obtaining using fast Fourier transformation. Second to last chapter introduces very measurement on the real device and in the last chapter these data are analyzed and more closely described.

Active sensors for detecting instantaneous stress and strain values
Vychopeň, Petr ; Kandus, Bohumil (referee) ; Podaný, Kamil (advisor)
Sensors used in engineering are divided into different kind of groups. One of them are an active sensors, which include inductive, photoelectric, thermoelectric, pyroelectric and piezoelectric. Based on literary study there are introduced, on the first place, the basic concepts related to the general characteristics of sensors, their inclusion in the measuring process and then describes the basic division, each operating principles, dependence and characteristics, specific examples of the applications in technological process and finally their advantages and disadvantages.
