[Hint this sub-circuit should be able to give a net resistance value that ranges from 100 22 to 1402 as the variable resistor is tuned. Select resistor values for the balance sub-circuit that will allow you to balance the bridge. Add variance to these resistors by making the value of each 12x and 12y where x is the last digit of your 800 number and y is the next to last digit. Choose nominal 120 resistors for R and R. To make this exercise more realistic, you will generate a variance in the resistor values that you use. ![]() AD623 RE -IN NE -V RO Vs OUTPUT REF Wheatstone Bridge Figure 3: Amplified Wheatstone Bridge The strain gauge that you will be using is the Vishay general purpose strain gauge with a nominal resistance of 120.02.
