Hi All,
Struggling with a design question and how to get started with it.
A strain gauge sensor, R4, has a resistance value from 110 ohms (no deflection) to 110.7 (full deflection). I need to design a circuit that will use this sensor to produce a voltage in the range [0.0V, 3.0V].
I need to calculate the value of Vsensor in the circuit.
Let R = R1 = R2 = R3, prove that Vsensor = Vs x (R-R4)/2R.
I am struggling to see what voltage I would give Vs.
Any help would be appreciated.
Nath.
