Hi,
Simple strain guage measurement circuit has been designed using wheatstone bridge and instrumentation amplifier is used to increase the gain of the bridge output.
with the help of LTspice IV tool, the circuit was simulated and accordingly results were tabulated.
The question is deviation is observed from theoretically calculated output voltage value and measured value (i.e simulated). Please do give your insights on reason for this deviation.
For further details about the circuit design please refer the attachment.
Kind Regards,
