Abstract

Tema završnog rada je ispitivanje karakteristika termostatirane uljne kupke. Kupka se koristi kao zona kontrolirane temperature u čijem su radnom volumenu smješteni etalonski otpornici. U radu će se dati opis termostatirane kupke i njenih elemenata, uz postupak ispitivanja zone kontrolirane temperature koji uključuje određivanje horizontalnih i vertikalnih temperaturnih gradijenata te stabilnosti temperature u radnom volumenu kupke.
U radu je opisana i objašnjena korištena metoda ispitivanja uz prikaz pripadajućih shema, parametara i formula.
Na kraju rada, pokazan je postupak procjene utjecaja karakteristika termostatirane kupke na nesigurnost električnog otpora etalonskih otpornika koji su smješteni u njenom radnom volumenu. Ispitivanje karakteristika kupke i pripadna analiza rezultata rađena je prema proceduri Laboratorija za procesna mjerenja na Fakultetu strojarstva i brodogradnje u Zagrebu.

Abstract (english)

This final thesis examines the characteristics of a thermostatic oil bath. The bath is used as a controlled temperature zone, within whose working volume reference resistors are placed. The thesis provides a description of the thermostatic bath and its components, along with the procedure for examining the controlled temperature zone, which includes determining horizontal and vertical temperature gradients as well as temperature stability within the bath's working volume. The testing method is described and explained, including accompanying diagrams, parameters, and formulas.
At the end of the thesis, the procedure for assessing the influence of the thermostatic bath's characteristics on the uncertainty of the electrical resistance of standard resistors placed in its working volume is presented. The testing of the bath's characteristics and the associated analysis of the results were conducted according to the procedure of the Laboratory for Process Measurements at the Faculty of Mechanical Engineering and Naval Architecture in Zagreb.
