PAV3000 Series
AIR VELOCITY SENSOR 131 E. Brokaw Road | San Jose CA 95112 | +1 (408) 392-0989 | info@posifatech.com | www.posifatech.com
DESCRIPTION
PAV3000 was designed as an economical high- performance air velocity sensor for thermal management in even the most space constrained locations such as data center server farms. Unlike thermistor based solutions, the Posifa MEMS sensor core is minimally affected by ambient temperature changes and provides instant real time feedback on proper air flow at the server blades. PAV3000 features Posifa’s third-generation thermal flow die, benefiting from the latest innovations in microfabrication. The sensor die uses a pair of thermopiles to detect changes in temperature gradient caused by mass flow, delivering excellent signal-to-noise and repeatability. The “solid state” thermal isolation structure on the sensor die eliminates the need for surface cavity or fragile membrane used in competing technologies, making the sensor resistant to clogging and pressure shock.
FEATURES
The PAV3000 series is surface mountable (SMD) and • Unsurpassed performance in a robust and cost provides a digital I2C output. effective package • “Solid state” sensing core (no surface cavity
