The objective my diplom work is acquaint with problems non-contact temperature measuring. After division kinds pyrometers and description their part I'm deal with calibration pyrometer and errors at measuring. To comparing contacting and non-contacting thermometer I'm used measuring on model.

Klimatologie vertikálního teplotního gradientu ve spodní a střední troposféře Climatology of temperature lapse rate in the lower and middle troposphere Abstract The main objective of this thesis is synoptic-climatological analysis of the temperature lapse rate (γ) in the lower and middle troposphere above the boundary layer at mid-latitudes of the northern hemisphere. The main part of the background research summarizes current knowledge about the mechanism of air temperature change with altitude, the effect of water vapour on γ, and stability conditions in the atmosphere. Radiation and net radiation are discussed to be one of the key factors influencing the behaviour of γ. The following chapter is summarizing findings about temporal and spatial variability of γ. The analysis of γ calculated from 850 and 300 hPa radiosounding data from Praha-Libuš is the core of this thesis. Results were used to describe annual variation of γ. Daily variation was not observed at this altitude. Further, the relationship of γ with air flow direction and Hess-Brezowsky synoptic types was analysed. The results show that the air flow direction and the synoptic situations together with the radiation and the humidity of atmosphere influence the value of γ. Based on the analogous analysis of γ in Poprad-Gánovce were results from...

he objective diploma work is clarification problems contactless temperature measuring and objective comparison measurement contact thermometer and pyrometer on laboratory model.

The goal of this thesis is the incorporation of the contactless measurement of surface temperature among other methods of temperature measurement. Technical preparation for experimental measuring on the machine-tool. Comparison of influence of cutting conditions on the development of surface temperature of workpiece during the machining process with usage of the camera ThermaCAM CS2000. The economical analysis of the contactless measurement of surface temperature is determined in the last part of this thesis.

Detailed introducition of non-contact temperature measurement and correct settings of the measurement device, which has great influence on correct temperature determination, is the aim of this diploma thesis. The experimental laboratory was established to verify dependencies by Compaq CM non-contact thermometer. Conclusions and recomendations are deduced from the measurement results and their analysis.

Diagnosis temperature is one of the most important disciplines. We meet it in everyday life, but it is very important for all sectors of industry. This is a measurement providing an immediate state of the measured object. Contact measurement of different temperature sensors and contactless measurement using thermal imagers. The important part is the measurement of temperature rise of induction motor. Part of the work deals with losses in the electric motor. These losses are converted into heat, which affects from various parts of the machine. Correct identification of the temperature field is important in helping to design the cooling system of the instrument. Virtually the data obtained are compared with theoretical data. We will capture part of the device and realize thermal simulations in a suitable simulation program. We propose modifying the cooling machine and the resulting data from the simulation compares.

The thesis deals with formation of a workplace for preparation gaseous mixtures and their future usage. The main goal of the thesis is testing of new materials which have suitable usage as catalysts. Gaseous mixture is prepared by calorimetric mass flow meters with control valve and multiposition microelectric valve actuators. The next part describes measuring of pressure and temperature and controlling of furnace temperature. The thesis deals with specifications of all devices, their circuitry, communication and program controlling. All devices are controlled by computer with program which is programmed in LabVIEW.
