AFM-120NC產(chǎn)品概述
The air-flow monitor provides a simple alternative to indicate positive or negative air flow of fans. When properly installed and connected in series with an optical (i.e. LED) or audible signaling device, a bidirectional switch will activate an electrical contact if the air flow of the fan falls below 8.2 Ft./s, turning the signaling device on or off.
