AVFS-1

AVFS-1 is a 80-250AC/DC power thermo air flow switch, specifically designed to monitor air flow in ducts and provides a 3A contact output to indicate a change or loss of flow. The AVFS provides a ±5% set-point repeatability across a full scale range of 1-10m/s (197-1969fpm) and includes a mounting bracket for quick duct mounting. Typical applications include fan monitoring, filter monitoring, damper feedback and air handlers.
