Calibration and evaluation of data from strain gauges
Dubina, Jozef ; Mačák, Martin (referee) ; Vyroubal, Petr (advisor)
This thesis describes calibration and evaluation of data measured from tensometric sensors. The labour describes tensometers in general, their functions, aplications and principle of operation. Loading data from tensometric sensors is next part of this labour, where are information how to convert analog to digital signal output, which is ready for processing and shows real values. After signal is converted to digital signal, is needed to calibrate tensometers to receive high precission values of weight according to reference load. Thesis describes choices of electronic and mechanical components for building digital scale. Software developing for this electronic equipment is described in next part of thesis.

Beehive Scale
Žilka, Martin ; Musil, Tomáš (referee) ; Novák, Lukáš (advisor)
The focus of this bachelor‘s thesis is to retrieve available information about possibilities of solution design of a beehive scale, which should be used in the countryside and has the option of remote data sending. The next step is to build a prototype of that scale. The introductory part contains a parameter description of eight types of commercial beehive scales. The next part is focused on principles, positives and negatives of some commercial weight sensors. The following section deals with communication interfaces used in the IoT. In conclusion is made a selection of the most appropriate technologies for remote weighing beehives, based on the previous research. The last part is devoted to the description of prototype construction.

Design of experimental device for visualization of axial forces in bolted connections
Ptáček, Tomáš ; Galas, Radovan (referee) ; Svoboda, Petr (advisor)
In the bachelor's thesis is created design experimental device that will be able to measure preload in bolted joints. The first part of thesis deals with research study of the current state of knowledge of bolted joints, depending on the use of different types of lubricants. According to informations, 3 different variants are introduced. The selected variant is described in detail with their advatnages and disadvantages. The final design is developed into technical drawing and electronic 3D models.

Extending the Laboratory Educational Kit PIC Edu Kit with a Set of Wireless Sensors
Hanuš, Tomáš ; Najman, Jan (referee) ; Sova, Václav (advisor)
This thesis describes the design and implementation of extension of laboratory training model PIC Edu Kit. It is about set of wireless sensors. These sonsors have to measure temperature and deformation. Mesure of temperature was realized by temperature resistive sensor Pt100 and deformation by resistive tenzometr. These wireless moduls comunication on protocol Wi-Fi. In this work is introduced propose of measuring dictucts for measure of temperautre and deformation. There is evidenced their realization, showed software for receiving dates on PC and programme for the microcontroler.

Tensometric measuring
Trojan, Vítězslav ; Kandus, Bohumil (referee) ; Podaný, Kamil (advisor)
This work is engaged in tensometric measuring. This work reports basic principles of tensometric measuring and problems connected with measurements. Different types of tensometres and their applications are described and elemental exercisee for common kinds of strain is infered. Suitability of tensometric sensor usage in mechanical engineering is discussed.
