Temperature sensor PAV1000

flowmass flowmedical

PAV1000 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. PAV1000 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. The PAV1000 series is available with analog voltage output trimmed at zero and full scale and digital I2C output.
