Upgrade Thermal Chamber
Pagáč, Radek ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
The target of this work is to modernize air-conditioning control of the unit Thermal Chamber. The old air-conditioning unit will be renewed by replacing old one by new one, microcontroller-driven control unit, trough which it will be possible to show the current and desired temperature LCD. Theoretically description of the components and methods of measuring the temperature and environment for the creation of the microcontroller is shown before construction.

Accuracy of body temperature measurement using infrared technologies
Mezera, Jiří ; Chmelař, Milan (referee) ; Provazník, Ivo (advisor)
This thesis deals with the measurement of body temperature using the infrared thermometers. The literature research is devoted to the description of the human body temperature, methods of its measurement and types of thermometers. The theoretical part further examines the infrared radiation, the principles of measurement, physical quantities, laws of infrared radiation, types of detectors and measurement uncertainties. The practical part focuses on experimental measurements with selected kinds of thermometers and verifying their accuracy. Finally, an experimental procedure has been designed which has then been used for the clinical measurements of body temperature under various conditions and their subsequent statistical evaluation.

Laboratory heating of MV cables
Vala, Martin ; Lázničková, Ilona (referee) ; Krbal, Michal (advisor)
This thesis deals with options of laboratory heating of high voltage cables. First part of the work is reserved for description of heat as physical phenomenon and quantities connected with the heat. Second part deals with options of temperature measurements of objects in practical use and third part of the work deals with options of cables heating regarding the measurements according the ČSN rules. Practical part of diploma thesis is focused on physical phenomenon description, being under way during measurement using selected methods in individual components and optimization of results for practical measurements.

IR thermometer
Šolc, Radek ; Chmelař, Milan (referee) ; Rozman, Jiří (advisor)
This bachelor’s thesis deals with the issue of temperature measuring with the use of contactless thermometer. The thesis examines the physical findings, detectors, methods for contactless temperature measurement. Practical part consists of system design. Suitable detector, signal processing system and evaluation of temperature were chosen. According to the system design were created circuit design solution and printed circuits boards’ design of IR thermometer.

Dynamic properties of thermometers
Tomšej, Radek ; Závorka, Dalibor (referee) ; Himr, Daniel (advisor)
This bachelor thesis deals with temperature measurement. The introduction describes the individual methods including the principles on which the methods are based. Furthermore, it presents the suitability of these individual methods, including the properties of thermometers based on the given methods. The experimental part of the thesis evaluates the practical measurement of temperature and proposes the design methods of determining the temperature in a time much faster than the response time of the thermometer.

Measurements of small flow rates
Lorenc, Dominik ; Šedivá, Soňa (referee) ; Mancl, Vlastimil (advisor)
The thesis deals with the extension of the laboratory fixtures with a~measuring track designed for the measurement of small fluid flows, on which the thermal flowmeter is tested. The used calibration methods are examined and the track is then subsequently constructed. A~measurement operating program is also developed to set the measurement parameters and to store the measurement data in the required format. The parameters and characteristics of the reference scale used and the thermal flowmeter provided are then measured on the constructed track. The measurement results are presented and the uncertainties of the selected flow rates are determined.
