6 FAQs about [Does the capacitor have the function of a diaphragm ]
How does a diaphragm and capacitor form a differential variable separation capacitor?
The sensing diaphragm and capacitor thus form a differential variable separation capacitor. When the two input pressure are equal, the diaphragm is positioned centrally and the capacitances are equal. A difference in the two input pressures causes displacement of the sensing diaphragm and is sensed as a difference between the two capacitances.
How does a capacitor work?
An electric field forms across the capacitor. Over time, the positive plate (plate I) accumulates a positive charge from the battery, and the negative plate (plate II) accumulates a negative charge. Eventually, the capacitor holds the maximum charge it can, based on its capacitance and the applied voltage.
How does a diaphragm change electrical capacitance?
The electrical capacitance of the capsule changes whenever variations in air pressure cause the distance between the diaphragm and backplate to change, and if a fixed electrical charge is placed across the capsule, the voltage on the diaphragm is modulated by the sound pressure to produce a small electrical signal.
How does a capacitor pressure sensor work?
The Capacitive pressure sensor operates on the principle that, if the sensing diaphragm between two capacitor plates is deformed by a differential pressure, an imbalance of capacitance will occur between itself and the two plates. This imbalance is detected in a capacitance bridge circuit and converted to a D.C. output current of 4 to 20 mA.
