1.1. Description of the new measurement principle
The presented transducer consists of a liquid filled elastic measuring cell, as presented in [1] in more detail,
concentrically enclosed by a pair of half-shell shaped electrodes, cf. fig. 1. The elastic wall of the measuring cell
changes its shape, mainly in diameter, with respect to the hydraulic pressure inside the cell. The associated change
in the inner volume, thus the amount and distribution of the dielectric liquid inside the cell changes the capacitance
of the electrode arrangement, which is employed to extract pressure dependent signals
