Monitoring system for a movable component connected to a stationary component

A monitoring system for a movable component connected to a stationary component, the monitoring system being connected to a processor, and the monitoring system comprising:

• an acoustic sensor placed in the movable component, the acoustic sensor comprising two independent electrical terminals;
• a first amplifier placed in the movable component, the first amplifier comprising two independent electrical input terminals and two independent electrical output terminals;
• a contactless communication unit comprising a first transceiver placed in the movable component, and a second transceiver facing the first transceiver and placed in the stationary component;
• and
• a transmission line defining a signal path, the signal path being fully differential throughout the transmission line, and the transmission line comprising;
• a first connection line comprising two independent electrical leads, each of the two independent electrical leads of the first connection line connecting an independent electrical terminal of the acoustic sensor to a corresponding independent electrical input terminal of the first amplifier;
• and
• a second connection line comprising two independent electrical leads, each of the two independent electrical leads of the second connection line connecting an independent electrical output terminal of the first amplifier to the first transceiver.
