Capacitive Silicon Differential Pressure Sensor

Proceedings of the International Solid-State Sensors and Actuators Conference - TRANSDUCERS '95, 2005
A capacitive differential pressure sensor based on silicon bulk micromachining is presented. This sensor, which is part of a flow metering system, transforms the differential pressure delivered by a fluidic oscillator into capacitance variations. These variations are then converted by an ASIC into a digital output signal.
