Current difference integration circuit for outputs of sensor measuring physical parameter has single integrator receiving output of difference circuit receiving outputs from sensor
A control current for an electrical sensor (1) is fed to sensor modules in a symmetrical arrangement producing two output currents (I A, I B). The midpoint of the sensor is earthed, and the output conductors (2,3) are connected to the + and - input terminals of a differential amplifier (6). The amplifier output is passed to an integrator circuit (7) which produces an output signal v(k integral (I A - I B)dt).
