Abstract

Tema ovog rada je kalibracija NTC otporničkih osjetila. U prvom dijelu rada definirane su osnovne stavke i koncepti potrebni za razumijevanje postupka mjerenja i kalibracije. Temeljne definicije odnose se na temperaturu, termometre, vrste termometara i povezanosti otpora, temperature i otporničkih termometara. Definirani su načini spajanja osjetila s mjernim instrumentom i popratne sheme.
Nakon za razumijevanje rada neophodnog teoretskog dijela, slijedi sam postupak mjerenja i analize mjernih rezultata. Opisana je laboratorijska oprema, uređaji, postupak mjerenja, a zatim provedena analiza programa korištenog za mjerenje. Program je izrađen u alatu LabVIEW i opisane s u njegove osnovne komponente i način rada.
Zadnji dio rada sastoji se do analize i obrade dobivenih rezultata te njihova korištenja u svrhu određivanja funkcije kojom možemo dovoljno precizno odrediti temperaturu za zadanu vrijednost otpora termistora.

Abstract (english)

This bachelor thesis describes the procedure of the NTC resistance sensors calibration. Basic items and concepts necessary for understanding the process of measurement and calibration are described in the first part of the paper. These definitions refer to temperature, thermometers, thermometers types and relation between resistance, temperature and resistance thermometers. Sensors and measuring instruments connection methods are also defined with appropriate diagrams.
Second part of the paper consists of measurement procedure and analysis of measurement results. Laboratory equipment, apparatus, measurement procedure and program used for measuring are also described and analyzed. Program was created in LabVIEW and its basic components and operations are defined.
The last part of the work contains analysis and processing of the results and their use in order to determine the functions that can be accurate enough to determine the temperature for a given resistance value of the thermistor.
