1. A capacitive sensor device for determining a distance between a rigid body and another rigid body in a system for contactless linear displacement along a linear displacement path of the rigid body relative to the other rigid body, the capacitive sensor device comprising:
a capacitive sensor component with a first sensor node mounted to the rigid body and a second sensor node mounted to the other rigid body;
a transmission component having at least a first input node for receiving an input signal as well as an output node for providing an output signal representative of the distance;
a frequency-dependent input signal generator operatively connected to the first sensor node of the capacitive sensor component and
the first input node of the transmission component being operatively connected to the second sensor node of the capacitive sensor component.
