From the results of the experimental phase determination to raise the pressure of getting that pressure in the range of 0-18 kPa, as shown in Figure 4.5, it was found that during the period of 0-0.15 millimeters to raise the pressure of the receipt of the results of experiments with values correspond to values from the analytical methodology and values from a Java Lor.Substitutes the value range program, COMSOL, but to raise the value, the more the values from the analytical methodology has a value different from the value from the Java long because the equation method to raise the stage by analytical methodology that is based on an analysis of the value of the phase under sommutithan to raise.Wokong get the pressure plate is less (small deflection) should not exceed half of the thickness of the pad pressure or receiving approximately 0.154 mm (0.307 sheet thickness, mm), so a greater distance to to raise them up from analytical to become inaccurate and inconsistent with the values from the Java long.In addition, during the more than 10 kPa pressure range of pressure to raise the sheet obtained from the experiments is greater than the value that is derived from the Java long, because in a real experiment, when there is pressure. Base plates, anchor getting the pressure between the support and the simple fixed support [19] at the time of a Java long value from the base case based on a fixed support, so make up your plate to raise the stage received pressure from higher values result values from a Java try.From the calibration graph, pressure range 0-17.4 kPa pressure found is likely to increase as pressure increases. For use in the range 0-8.7 kPa is the relationship between the value of the outgoing voltage and pressure is linear and the sensitivity values equal to 1.5 mV/V/kPa and is equal to 3.28% FSO. error by Dong won beam tables displayed error of pressure against the pressure, kPa range 0-17.4 in table 4.4.
