Abstract

A measurement system including a reference resistive sensor traversed by a reference current, with a reference arm having a reference resistance and being traversed by the reference current in order to produce a reference voltage between its ends, at least one measurement resistive sensor traversed by a measurement current that depends on a measurement taken by the measurement resistive sensor, a measurement mirror arm traversed by a current, and a device for measuring the difference between the measurement current and the current traversing the measurement mirror arm. The resistance of the measurement mirror arm of each measurement resistive sensor is equal to the reference resistance and the measurement system further includes a device for applying, to each measurement mirror arm, the reference voltage. The device for applying the reference voltage being designed to the isolated to a current of the measurement mirror arm when the reference voltage is applied.
