Diffusion Silicon Pressure Sensor utilizes the principle of piezoresistive effect, adopts integrated process technology to dope and diffuse, and forms a strain resistance along the characteristic crystal orientation on the single crystal silicon wafer to form a Wheatstone bridge. By using the elastic mechanical properties of silicon materials and performing anisotropic micromachining on the same silicon-cut material, a diffused silicon sensor integrating force-sensitive and force-electric conversion detection is fabricated.
The pressure of the diffused silicon pressure sensor acts directly on the diaphragm of the sensor (stainless steel or ceramic), causing the diaphragm to produce a micro-displacement proportional to the pressure of the medium, causing a change in the resistance of the sensor, and detecting this change with an electronic circuit. And convert and output a standard measurement signal corresponding to this pressure.
