Laboratory thermometer based on Pt100 sensor
Konečný, Jiří ; Murina, Milan (referee) ; Steinbauer, Miloslav (advisor)
This text put mind to questions of touch temperature measurement. Describes the various of electrical temperature sensors, which are divided in accordance with physical principles, on which they work. For each sensor are given its characteristics, such as temperature range, tolerance, advantages and disadvantages, or the measuring circuit. The sensors are described mainly by mathematical equations and polynomials. Their knowledge is needed for the construction of additional circuits or devices for processing information from sensors. In this work is also suggested a completely involvement of digital thermometer, which uses a Pt100. According to this proposal is made a prototype piece.

Heat technological process model
Krásenský, Jan ; Dokoupil, Jakub (referee) ; Malounek, Petr (advisor)
This work presents possibilities of X20AT2222 and X20AT2402 measuring cards. It describes design of physical heat tunnel with three sections, where each one has own heating elements. In detail is described technical solution and structure of model. Subsequently is designed controller and process visualization for PLC. Based on identified system and model structure is created system simulation in Matlab Simulink.

Thermostat for measuring passive component controlled of AVR
Demjanics, Ferenc ; Koňas, Petr (referee) ; Roubal, Zdeněk (advisor)
The aim of this work is to familiarize with the design of the thermal test chamber to measuring passive components. Show features and involvement of selected circuits that ensure reliable operation of the device. For the realization of the role are the most important the Peltier cells and temperature sensors. But they can not work without the control unit. The control unit provides the necessary communication with each component and also with user. For this purpose we made a selection of suitable type of microcontroller and communication equipment (matrix keypad, LCD, buttons and LEDs). Subsequently was designed the algorithm to control the thermostat suitable for using in students training. The algorithm was written in the microcontroller in form of a program. There is also implemented a PSD controller in the program, which evaluates the data collected by a sensor. Then set the correct function of Peltier cells. After the thermostat was designed and realized, test measurements were performed and the results were documented and evaluated.

Microcontroller based temperature controller
Perůtka, Martin ; Fiedler, Petr (referee) ; Bradáč, Zdeněk (advisor)
The aim of the work was to design and carry out a microprocessor driven temperature controller which will be operated by PC or immediately by its own control panel. The controller should serve, for example, as a regulation of temperatures in rooms, in ovens where electrical energy is used for heat production. This controller is able to measure temperature through connected temperature sensors, which means a thermistor PT1000 and a thermocouple type K, and to regulate temperature by the help of a heating body connected to the power output part of the controller.In this piece of work there is an issue of temperature measuring by the help of thermocouples and thermistors analysed, there are also mentioned the means of controlling and switching of alternating electrical tension for power operating and analysis of an issue of device connection and communication by the help of RS232 interface and USB with PC. The work also deals with a design of PSD controller with its subsequent realisation. The controller is tested on a micro-condensational siccative oven developed for the UTB research in Zlín.
