Technical Electrodynamics| Summary: | Shown two main areas, which are used to create the transducers to work in conjunction with capacitive sensors. In the first case the measuring circuits are based on equilibration circuits alternating current, in particular bridges or compensatory-bridge circuits and their version – switching balancing device, also known as charge-balancing device. In the second case, transducers are based on single-crystal structures completed, converters "Capacitance to Digital Converter » (CDC) uses the architecture and circuitry of the sigma-delta modulation converters, resulting in a compact techproduct in the form of inexpensive mass-produced chips. Described circuit and operational features discussed converters, shown the advantages and disadvantages of both types of devices, as well as the preferred areas application. Shown the examples of transducers. References 22. Figure 3. |
