Detailed explanation of capacitive pressure sensor in one article 1

In modern industry and scientific research, measuring and monitoring pressure is crucial. Capacitive pressure sensors, with their high sensitivity, long lifespan, and ability to maintain stability over a wide temperature range, have become the preferred pressure measurement tool in many fields. This article will provide a detailed introduction to the working principle, structural design, application scenarios, challenges, and future development directions of the FSBB30CH60F capacitive pressure sensor.

The core working principle of capacitive pressure sensors is based on the basic formula C=ε A/d of capacitance, where C is the capacitance, ε is the dielectric constant, A is the electrode area, and d is the electrode spacing. When the sensor senses external pressure, it will cause a change in the electrode spacing d, resulting in a change in the capacitance C. By measuring the change in capacitance, the magnitude of pressure can be accurately measured. diode
