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 highperformance 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
provides a digital I2C output. • Unsurpassed performance in a robust and cost
effective package APPLICATIONS • “Solid state” sensing core (no surface cavity
or fragile membrane) resistant to clogging and …
