Synopsis
This experiment was mainly purposed to analyze working principle of Bourdon tube pressure gauge. The other aim of the experiment is to calibrate manometer by reading off the pressure derived from applying weights to piston manometer. Realization of working principle of piston manometer and identification of systematic errors are other major objectives of this experiment. The experiment was carried out in two steps. In the first part of the experiment, in order to calibrate manometer the cylinder was filled with oil, then by loading the cylinder with weights, which held on the weight support, and by regulating the load unit using pressure relief knob, the pressure increase was recorded. The pressure applied by loading weights was recorded each time. In the second part of the experiment, piston manometer was unloaded and obtained pressure was noted each time again. After measuring pressure values for each step, the average and limiting pressure values of two steps were calculated. Then, as a result, comparing theoretical and experimental values systematic deviations were derived for each step of the experiment. Finally, the experimental-theoretical pressure dependence graph and the graph of dependence of relative error on experimental pressure were sketched. Moreover, the report encompasses industrial…show more content… By inserting weight support and loading weights on piston manometer, which is connected with Bourdon tube pressure gauge, the oil starts to move towards Bourdon tube. The Bourdon tube pressure gauge mainly consists of Bourdon tube (3) at fixed position, scale (1), pointer (2), gearing (4) and tie rod (5). When the oil starts to flow through fixed place of tube, it begins to expand from 6th to 7th position. This happens due to the force increase, which is directly proportional to the area under constant pressure from the equation indicated
