Abstract
U radu su opisane vrste termometara u kontaktnoj termometriji i prikazane su metode za procjenu mjerne nesigurnosti mjerenja. Posebno je opisan utjecaj provođenja topline kroz tijelo termometra, utjecaj izmjene topline termometra konvekcijom i utjecaj izmjene topline zračenjem termometra s okolinom na mjernu nesigurnost. Prikazan je zajednički utjecaj više parametara na mjernu nesigurnost temperature za dispozicije termometra u raznim proračunskim uvjetima. Nakon obrade teorijskog dijela izveden je eksperimentalni rad. U eksperimentalnom dijelu, koji je izveden u Laboratoriju za procesna mjerenja, Fakulteta strojarstva i brodogradnje, Sveučilišta u Zagrebu, ispitan je utjecaj emisijskog faktora površine termometra na mjernu nesigurnost temperature. Prije izvođenja eksperimentalnog rada platinski otpornički termometri su umjereni u kupki s etalonom. Na kraju je prikazana usporedba između procjene rezultata i rezultata dobivenih mjerenjem.
Abstract (english)
In this paper therometeres in contact thermometry are defined and methods of evaluating measurement uncertainty are presented. Especially are described effect of heat conduction through body of thermometer, effect of heat convection and effect of thermometer radiation with ambient on measurement uncertainty. Combined effect of several parameters on temperture measurement uncertainty for thermometer dispositions in different estimate procedures is presented. After processing the theoretical part, experimental work is performed. In experimental part, which was performed in Laboratory for Process Measurement, Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb, effect of emissivity of the thermometer surface on temperature measurement uncertainty is tested. Before the execution of the work, platinum resistance thermometers are calibrated in owerflow bath with standard thermometer. At the end, comparison between evaluated results and experimental results is presented.
