Sensirion CMOSens gas-flow and differential-pressure sensors have been produced with integrated intelligence in large quantities for several years. Produced on a silicon base by standard CMOS processes, the sensors are successfully used worldwide in several products and markets. Production is now enhanced to 8-in. wafer handling, so the high-performance gas-flow and differential-pressure sensors can be produced even in millions at a high level of quality while reducing the already-low costs. The sensors feature built-in self-test algorithms, which make them a good fit for demanding applications, for example, medical or gas burner control applications.
