Consider all resistors to be of equal value except for Rgain. If the outputs of op-amp 1 and op-amp 2 are Vo1 and Vo2 respectively, then the output of the difference amplifier is given by, Vout = (R3/R2) (Vo1-Vo2). Not all amplifiers used in instrumentation applications are instrumentation amplifiers, and by no means are all in. Connecting the Earth ground in this way should reduce or eliminate any electronic noise.
