EXCITATION CIRCUIT FOR DC SENSORS |
摘要 |
Excitation circuit for at least one DC sensor, comprising a digital regulating computer linked to a main chain and to a regulating loop. The main chain comprises a digital/analog converter linked to the sensor by a direct amplified pathway and a reverse amplified pathway to emit sensor excitation signals having a differential-mode DC component. The regulating chain comprises an analog/digital converter linked to the amplified pathways, the circuit comprising a monitoring chain which is linked to the computer in parallel with the converter so as to emit signals as a function of an AC component of the signals tapped off the amplified pathways. The digital computer is devised so as to inject a common-mode sine wave onto the excitation signals and to analyse signals at the output of the monitoring chain and signals at the output of the analog/digital converter. |
