Abstract

U ovom radu dokazana je teoretska ovisnost ulaznih i izlaznih veličina, te je konstruiran i umjeren mjerni pretvornik sile u uređaju za mjerenje mase tijela preko frekvencije napete žice. Teoretski su obrazložene karakteristike mjerenja, značajke mjernog pretvornika, te općenito potreba za istim. Istaknute su poteškoće tijekom izrade i umjeravanja, te su dane smjernice za daljnja istraživanja. U eksperimentalnom dijelu ovoga rada konstruirana je i umjerena frekvencijska vaga. Dokazana je funkcionalnost metode te su eksperimentalni podaci popratili teoretsku osnovu. Mjerenje je brzo i jednostavno, a rad može poslužiti kao osnova za daljnja istraživanja ovisnosti frekvencije i mase, odabira materijala, te dimenzioniranja i konstruiranja vagi na navedenom principu.

Abstract (english)

In this paper, the theoretical dependence of input and output size is demonstrated, and force sensor in the device for measuring body mass over the frequency taut wire was designed and calibrated. Characteristics measurements, the transmitter features and generally need for them, are theoretically reasoned. Difficulties during the development and calibration are highlighted, and guidelines for further research are given. In the experimental part of this work, the frequency scale is designed and moderated. The functionality of the method is proven and experimental data covered the theoretical basis. Measurement is fast and simple, and the work can serve as a basis for further study of the frequency dependence and weight, material selection and dimensioning and construction of scales on the above principle.
