20.500.12556/RUL-83469 Termometer za merjenje temperature vode v oceanografiji A thermometer for the water temperature measurement in the oceanography Temperatura je ena najosnovnejših fizikalnih veličin in ima zelo pomembno vlogo tako v vsakodnevnem življenju, kot tudi pri nastanku, evoluciji in obstoju življenja na Zemlji. Oceani pokrivajo 71 % površina našega planeta in z povprečno globino 3,8 km tvorijo volumensko največji habitat na Zemlji. Natančno merjenje temperature voda ima zato veliko pomembnost, še posebej v današnjem času, ko je proučevanje klimatskih sprememb in globalno segrevanje zelo aktualno in, ko kakovostnih in sledljivih temperaturnih meritev oceanov še vedno zelo primanjkuje. Zato se diplomsko delo osredotoča, na načrtovanje in izdelavo termometra za merjenje temperature vode v oceanografiji. Razviti termometer se nato preizkuša v temperaturnem območju med 0 °C in 40 °C ter pod tlakom do 150 barov. Glavni del tega dela je tako namenjen metodologiji izbire komercialnega temperaturnega senzorja, njegovo adaptacijo za merjenje temperature v vodi, integracijo v celoten merilni sistem z mikrokrmilnikom in nenazadnje še testiranje njegovih zmogljivosti v akreditiranem laboratoriju. Izdelan termometer temelji na polprevodniškem integriranem nizko cenovnem senzorju nove generacije. Ta se je izkazal kot odlična izbira z nadpovprečnimi zmogljivostmi za svoj cenovni razred in enostavno integracijo v merilni sistem. Temperature is one of the most basic physical quantities and plays a very important role both in everyday life, as well as in the origin, evolution and existence of life on Earth. Oceans cover 71% of the surface of our planet, and with an average depth of 3.8 km form the largest habitat in volume on Earth. Accurate temperature measurement of water has a very important role, especially nowadays, when studying climate change and global warming are very current topics and because there is still a lack of quality and traceable ocean temperature measurements. Therefore, this study focuses on the design and development of thermometer for measuring the temperature of water in oceanography. The develop thermometer is then tested in temperature range between 0 ° C and 40 ° C and under a pressure of up to 150 bar. The main part of this work is also dedicated to the methodology for selection of the right kind of commercial temperature sensor, and its adaptation for the measurement of temperature in water. It also focuses on the integration of the entire measurement system using microcontroller, and finally testing of its properties in an accredited laboratory. The developed thermometer is based on a new generation of silicon bandgap temperature sensor, which is low in cost. This proved to be an excellent choice, because of its above average performance in its price range, and because of the simplicity of integration into the measuring system. izdelava termometra merjenje temperature v oceanografiji polprevodniški integrirani temperaturni senzor development of a thermometer temperature measurement in oceanography silicon bandgap temperature sensor true false false Slovenski jezik Angleški jezik Diplomsko delo 2016-06-16 08:22:31 2016-06-16 08:22:36 2022-08-01 23:22:44 0000-00-00 00:00:00 2016 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 33945 Kervina_Gregor_-_Termometer_za_merjenje_temperature_vode_v_oceanografiji.pdf Kervina_Gregor_-_Termometer_za_merjenje_temperature_vode_v_oceanografiji.pdf 1 22F6EA3A8735B217DABC7E63A486B530 57385e93333e5797bfad164e5986c237017661d24c554d71f742bbfd5ee47303 481830c5-a1ae-11eb-a523-00155dcfd717 20.500.12556/rul/1d7c0e07-bac9-41ba-915a-0b3b30be4ccc https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=86488 Fakulteta za elektrotehniko 0 0 0
