The Context

The PAV5000 features Posifa’s third-generation thermal flow die, which uses a pair of thermopiles to detect changes in temperature gradient caused by mass flow. Featuring a solid-state thermal isolation structure on the sensor die, the anemometer eliminates the need for surface cavities or fragile membranes used in competing technologies, making the device resistant to clogging and pressure shock. While traditional thermistor-based anemometer sensors connect to the circuit via a thin thread, the PAV5000’s sensing element consists of a solid silicon chip flush-mounted onto a PCB. This design makes the anemometer sensor robust against damage caused by vibration, dropping, or collisions.
