Piezoresistive silicon pressure sensor principles
2013-06-11
Principles: The media pressure directly work on the sensor diaphragm (stainless steel or ceramic), The diaphragm produces a micro-displacement which is proportional to the pressure from the medium, and make the sensor's resistance to change, an electronic circuit is used to detect this change and convert the output of the pressure to a standard measurement signal...
Advantage: There are a wide variety of mechanical sensors, such as resistance strain gauge pressure sensors, semiconductor strain gauge pressure sensors, piezoresistive pressure sensors,pressure sensors inductive, capacitive pressure sensors, pressure sensors and resonant capacitive accelerometer sensors. However, the most widely used is the piezoresistive pressure sensor, it has a very low price and high precision, and good linearity.
