Each AVTECH Air Flow 2 Sensor (NO) provides real-time recognition of air flow stoppage. This Air Flow Sensor is normally open and includes a mounting clip and clamp. Typical use is to monitor continuous air flow in an HVAC duct, under a raised floor, or near a fan on a rack cabinet or important server.
This is an instant ‘Plug & Play’ sensor via one of the switch sensor channels on the back of any compatible Room Alert ID box. Cable distance can be extended from the standard 25′ to approximately 900′ by using standard speaker wire, twisted pair or any reliable low voltage 2-wire cable. This air flow sensor switch is equivalent to the discontinued Stego Air Flow Sensor #01300.1.
