i am taking a +/-5 voltage signal is supposed coming from a torque sensor. this is supposed to be equal to 100 N*m. However, -5.04 volts is actually equal to 100 N*m and 4.85 volts is actually equal to 100 N*m. I need to scale this signal to a maximum input of 200 mV for display on a panel meter. I was just going to use a voltage divider going into a noninverting op-amp, but I am not sure what to do now that I know the negative and positive voltage signals don't match, I was told a differential amplifier would work for this, however, I am not quite sure of how to accomplish this, any help would be appreciated.
