Operational amplifier instrument circuit

The circuit's gain is veryeasy tocalculate. But this circuit also has a weakness: that is in the circuit, the two resistances must be replaced together, and they must be equivalent. Another weakness is, the first level op-amp dose not produce any useful gain.
