Air FLow Detector - This simple circuit uses an incandescent lamp to
detect airflow. With filament exposed to air, a constant current source is
used to slightly heat filament. As it is heated, resistance
increases. As air flows over filament it cools down, thus .… [Aaron Cake]
AirfLow Monitor Protects Components - 09/28/95 EDN-Design
Ideas....Many electronic components, including fourth-generation µPs, require
forced-air cooling. However, the reliability of electromechanical components,
such as cooling fans, lags behind that of electronic devices. Even if a fan does
not fail, blockage of the air-intake vents can reduce airflow. The circuit in
Fig 1 helps you protect against high-temperature-induced system failures
by monitoring the performance of the cooling system.... [Design Idea by Wes
Freeman, Analog Devices, Santa Clara, CA]
