20.500.12556/RUL-118041 Ovrednotenje kapljevinske termostatirane kopeli za umerjanje uporovnih temperaturnih zaznaval Evaluation of a liquid thermostatic bath for calibration of resistance temperature sensors Uporovna temperaturna zaznavala, kot je Pt100, zaradi intenzivnega prestopa toplote najpogosteje umerjamo v kapljevinskih termostatiranih kopelih. Te kopeli morajo imeti skupaj s referenčnim termometrom mnogo manjšo merilno negotovost od umerjanega termometra. V zaključnem delu bomo preverjali ustreznost termostatirane kopeli za umerjanje Pt100 termometrov točnostnega razreda A. Pobližje si bomo ogledali prispevke homogenosti, stabilnosti in zasedenosti na merilno negotovost pri delu s kopeljo. Resistance temperature sensors such as Pt100 are, due to intensive heat transfer, most often calibrated in liquid thermostatic baths. Among with reference thermometer, these baths have to have significantly lower measurement uncertainty than thermometers that are being calibrated. In this final thesis, we will asses the usability of a liquid thermostatic bath for Pt100 class A calibration. We will take a closer look at homogeneity, stability and loading factor contributions to measurement uncertainty of a bath. temperatura termostatirana kopel Pt100 zaznavalo merilna negotovost umerjanje temperature thermostatic bath Pt100 sensor measurement uncertainty calibration true false false [M.
