In various industrial and commercial applications, accurate pressure measurement is essential. One of the most reliable and widely used technologies for pressure sensing is capacitive ceramic pressure sensors. These sensors leverage ceramic materials' robustness and the precision of capacitive measurement techniques to deliver highly accurate and durable pressure readings.
Understanding Capacitive Ceramic Pressure Sensors
Capacitive ceramic pressure sensors operate based on the principle of capacitance change. The sensor consists of a ceramic diaphragm and a reference electrode that form a capacitor. When pressure is applied, the diaphragm deforms, altering the capacitance. This change is then converted into an electrical signal, which can be processed for precise pressure readings.
Key Features and Benefits
