8.2: Capacitors and Capacitance

A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum, and, in that case, a

6 FAQs about [Working Principle of Differential Capacitor]

What is differential capacitance?

The latter is called the "differential capacitance," but usually the stored charge is directly proportional to the voltage, making the capacitances given by the two definitions equal. This type of differential capacitance may be called "parallel plate capacitance," after the usual form of the capacitor.

How does a differential capacitance sensor work?

The sensor, in turn, responds only to the difference in pressure between the ports. The differential capacitance sensor construction is more complex in this particular pressure instrument, with the plane of the sensing diaphragm perpendicular to the plane of the two isolating diaphragms.

What is a capacitance differential pressure transmitter?

What are differential mode inductors & capacitors?

The main use of differential mode inductors and differential mode capacitors. It can be seen that after the current flows through the differential mode coil, the magnetic flux inside the coil is enhanced, which is equal to the sum of two magnetic fluxes.

What are some examples of pressure instruments based on differential capacitance sensors?

A classic example of a pressure instrument based on the differential capacitance sensor is the Rosemount model 1151 differential pressure transmitter, shown in assembled form in the following photograph:

How does a diaphragm change capacitance?

The capacitance is the ability of the diaphragms to store electrical charge, and it is directly proportional to the distance between the diaphragms. As the pressure difference across the diaphragms changes, the diaphragms move, altering the distance between them and thus changing the capacitance.
