Characterization of thermostatic oil bath

Ovaj završni rad kao temu ima ispitivanje karakteristika termostatirane uljne kupke. U radu će se dati opis termostatirane kupke i njenih elemenata, uz postupak ispitivanja koji obuhvaća parametre koji imaju utjecaj na nesigurnost usporedbenog umjeravanja termometara, a to su određivanje horizontalnih i vertikalnih gradijenata te stabilnosti temperature. Na kraju rada, pokazan je i proračunski primjer ispitivanja s doprinosima kupke ukupnoj mjernoj nesigurnosti. Ispitivanje karakteristika kupke i pripadna analiza rezultata rađena je prema proceduri Laboratorija za procesna mjerenja na Fakultetu strojarstva i brodogradnje u Zagrebu.The topic of this paper is the examination of the characteristics of a thermostatic oil bath. The paper describes the thermostatic bath and its components, together with the test procedure which includes parameters affecting the uncertainty of the comparison calibration of thermometers, namely the determination of horizontal gradients, vertical gradients and temperature stability. At the end of the paper, the example uncertainty budget is shown, giving the contribution of the bath to the total measurement uncertainty when the bath is used for comparison calibration of thermometers. The calculation was made according to the procedure developed by the Laboratory for Process Measurement at the Faculty of Mechanical Engineering and Naval Architecture in Zagreb
