Brief Introduction
Capacitive pressure sensor are known for their high sensitivity and accuracy, especially in low-pressure ranges. They consume low power, making them ideal for portable or battery-powered applications. With a simple, durable structure, they are resistant to mechanical wear, providing reliable long-term stability. Additionally, they operate effectively across a wide temperature range, making them suitable for use in extreme environments.
The working principle of a capacitive pressure sensor is based on detecting pressure through changes in capacitance. The sensor consists of two parallel conductive plates with a fixed gap between them, forming a capacitor. When external pressure is applied, the distance between the plates changes slightly, causing a variation in capacitance. The internal circuitry then converts this capacitance change into a corresponding electrical signal, with the signal's magnitude directly proportional to the applied pressure.
