Miniaturized, low-power, high-resolution silicon barometric sensor
This miniaturized, low-power barometric sensor (< 2 mm2) is manufactured using silicon technology. Designed to operate in pressure environments ranging from one bar to several thousand bars, it is extremely sensitive and measures differences in altitude at a one centimeter level of precision. It is the only such device on the market with a self-test function that guarantees the reliability of its measurements.
The external pressure is calculated by measuring the deformation of a membrane that seals a vacuum chamber. Mechanical limits protect this membrane from breaking in case of excessive pressure. The sensor will work at temperatures up to 150°C..
This technology can also be used for various sectors of activity:
Automobile: tire pressure control, airbag, engine control
Aeronautics: tire pressure control, engine combustion regulation in relation to altitude
Medical: fall detector
Consumer markets: 3D indoor navigation, altimeter, onboard barometer
Oil exploration and extraction
Production, storage and distribution of
Monitoring of all types of industrial processes that require precise pressure measurements
