The differential piezo-resistive pressure sensor chip deposits a miniature piezo-resistive on a solid silicon film, and when powered by 5VDC, its piezo-resistive effect is used to sense the deformation of the film caused by pressure, providing an accurate, linearly related voltage output with the external sensed pressure.
Features
- Solid, MEMS technique, high reliability;
- Low cost, tiny size ,easy to use;
- Standard pressure range: 0－10KPa；0－40KPa；0－100KPa；0－300KPa ; 0－1000KPa ; 0－2000KPa.
Application
- Medical devices
- Monitoring
- sphygmomanometer
- Environmental measurement
- Consumer products
- Sports products
- Automotive pressure sensors
