- Measurement of strain and stress in pressure vessels plays a very important role in engineering, for example in the case of strain and stress analysis. By knowing the stress that occurs in the pressure vessel, the strain can be analyzed that occurs in the use of strain gauge. In this research, a strain gauge system has been designed using a strain gauge sensor based on Arduino Uno microcontroller to measure the pressure vessel experiment as a measurement object. The strain gauge sensor is mounted on the surface of the pressure vessel experiment which is connected to the compressor. The strain gauge sensor used has a voltage value of 350 ohms. This sensor is assembled with a series of Wheatstone bridges. Measurement using a pressure vessel experiment with a diameter of 65 mm and 0.2 mm thick. And compressors with a pressure strength of 0.033 Mpa and 160 watts of power. The output of the Wheatstone bridge is a voltage value but the resulting voltage value is very small so that it needs an instrumentation amplifier in the form of IC INA 125 of 1000 times the reinforcement. From the test results, there are 2 forces that occur in pressure vessel experiment, namely circumferential and axial forces. The test results show that the voltage that occurs in the circumferential force of 4.1740 Volts and has an increase so that 4.1965 Volts in line with the increase in pressure applied to the pressure vessel experiment. While the voltage that occurs in the axial force of 0.0628 Volts and does not experience a significant increase. So we can conclude this design can be said to be quite successful, this is indicated by the increase in stress on the circumferential force along with the pressure applied even though the stress that occurs on the axial force does not show the same thing
