Airflow sensors – AWM series
Contains advanced microstructure technology to provide a sensitive and fast response to flow, amount/direction of air or other gases. Airflow catalog listings start with AWM.
Airflow sensors – Zephyr series
Provide a digital interface for reading mass flow of air and other non-corrosive gases over the specified full scale flow span and temperature range. Their thermally isolated heater and temperature sensing elements help these sensors provide a fast response to air or gas flow. Catalog listings start with HAF.
