Figure 10: Output and input for Inductive Transducer Results for Strain Gauge Transducer: The process: The experiment was carried out by increasing the load on the beam and recording the voltage applied on the bridge. The next step was to prepare a table of the load, the bridge voltage and the theoretical stain. The table appeared as shown below: APPLIED LOAD (g) = L THEORETICAL STAIN (MS) = S BRIDGE VOLTAGE (mV) = V Theoretical Stain Gradient (S / L) Bridge Voltage Gradient (V / L) 0 0 0.1 #DIV/0! #DIV/0! 100 0.36 0.5 0.004 0.005 200 0.72 0.8 0.004 0.004 300 109 1.2 0.363 0.004 400 146 1.6 0.365 0.004 500 182 2 0.364 0.004 600 219 2.4 0.365 0.004 700 256 2.8 0.366 0.004 800 294 3.2 0.368 0.004 900 332 3.5 0.369 0.0039 1000 369 3.9 0.369 0.0039 0.294 0.00408 Table 3: Results for Strain Gauge Transducer Figure 11: The results or Strain Gauge Transducer The table below shows the data for bridge voltage against the theoretical stain.
