  • The Design of Stress-Strain Measurement System uses Rosette Strain Gauge sensor that can detect stress-strain in 3 direct axis direction. The object measurement material is a Stainless Steel beam, with a hinge-roller type foothold and a centralize loaded given three different load variations. The measurement system includes a Rosette Strain Gauge, an electronic circuit that includes a wheastone bridge with a Quarter-Bridge circuit configuration, Instrumentation Amplifier (IC INA 125P) and Microcontroller Arduino Uno. In this measurement system, the results of measurement are sent by Radio Telemetry through a radio wave network (Wireless) with a transmission distance of ± 1km. To display the results of measurements using a PC (Personal Computer) through Arduino IDE and Hterm software. As for creating graphics and storing data using PLX-DAQ and Microsoft Excel software. In testing the measurement system for stress-strain sensor, the Rosette Strain Gauge has obtained the average strain results on the X-axis 0.000112802, from the Y-axis with an average strain of 0.00023438, from the Ɵ axis with an average strain of 0.00023054. Whereas the Stress from the X-axis with an average stress of 21433013.33 N/m^2, from the Y-axis with an average stress of 44532200 N/m^2 and from the axis Ɵ with an average stress of 43802600 N/m^2.
