Measurement with pneumatic deadweight tester

Tema ovog završnog rada je opisati odabrani tip tlačne vage, opisati principe i postupke mjerenja, te provesti mjerenja na manometrima različitih klasa točnosti. Provedena su mjerenja na pet manometara različitog mjernog područja. Korištene su uljna tlačna vaga, plinska tlačna vaga i vakuum pumpa. Sva mjerenja zbog klasa točnosti provedena su prema C metodi. Korišteni etaloni bili su pretvornici tlaka sa pokazivačem, mehanički etalon sa kazaljkom i sklop klip-cilindar sa pripadajućim setom utega. Mjerni etaloni koji su korišteni umjereni su svakih godinu dana, a tlačne vage svakih pet godina. Klimatski parametri u laboratoriju za vrijeme mjerenja bili su kontrolirani i unutar granica dopuštenog.The theme of this final paper is to describe the selected type of pressure scale, describe the principles and measurement procedures, and carry out measurements on manometers of different classes of accuracy. Measurements were carried out on five manometers of different measurement scale. Oil deadweight tester, gas deadweight tester and vacuum pumps were used. All measurements due to accuracy classes were performed according to the C method. The etalons used were pressure transducers with a pointer, a mechanical etalon with a hand and a piston cylinder assembly with the corresponding weight set. The measuring etalons used are moderate every year and deadweight tester every five years. Used measuring etalons are calibrated every year and deadweight testers every five years. The climatic parameters in the laboratory during the measurement were controlled and within the permited limits
