Air Flow Measurements for Medical Applications
Air Flow Sensors
AV Sensors Mass Air Flow Sensors are equipped with state-of-the-art technology for exceptional performance. These sensors utilize dual silicon MEMS thermopiles, enabling precise detection of temperature gradient changes caused by mass flow. As a result, they deliver ultra-low noise to signal ratio, ensuring unparalleled accuracy and repeatability.
One of the key advantages of our sensors is the incorporation of a "solid-state" thermal isolation feature on the sensor die. This innovation eliminates the need for a surface cavity or a delicate membrane, making the sensor highly resistant to clogging caused by water vapor or dust particles. Additionally, the robust design ensures resistance to pressure shocks, ensuring reliability and longevity in demanding environments.
