摘要： A capacitive fill level measurement device with a fill level sensor having a plurality of sensor fields, electrical wires for electrically connecting the plurality of sensor fields to a multipole side of a selector switch, and a power supply and evaluation circuit electrically connected to a monopole side of the selector switch. The capacitive fill level measurement device can be made with simple production technology and thus economically for a host of different applications using a matrix of printed conductors which extend vertically and horizontally such that each horizontally extending printed conductor on one side is connected to one sensor field and on the other side connected to a vertically extending printed conductor. Each horizontally extending printed conductor is connected with a respective vertically extending printed conductor to form an electrical line or a part of an electrical line.

摘要： A capacitive sensor with at least one reference impedance (2) and at least one measuring condenser (3), at least one electrical alternating signal source (4), a current supply network (5) and an analysis unit (6) in which the reference impedance (2) and the measuring condenser (3) are connected via the current supply network (5) to the alternating signal source (4) and the analysis unit (6) in such a way that the charge and discharge currents of the reference impedance (2) and the measuring condenser (3) and/or an analysis signal from the analysis unit (6) that characterizes the charge and discharge currents of the reference impedance (2) and the measuring condenser (3) can be analyzed. As a result, the reference impedance (2) can be tuned. The capacitive sensor avoids—at least partially—drawbacks in the capacitive sensors known from the prior art in that the reference impedance can be tuned.

摘要： An admittance meter having an electrical alternating signal source, a diode ring operated as a synchronous rectifier with at least four diodes connected in series and in the same direction in succession, a measuring sensor, and an evaluation unit. The diode ring is subjected to an alternating signal via first second feed points, which are each connected via two series-connected diodes. The measuring sensor is connected to the first feed point, and the evaluation unit is connected to a first or a second measurement point of the diode ring. The first and second measurement points are each connected via one diode to the first and second feed points, respectively.
