The Dietz 103B - available from Variohm EuroSensor - is a sound option when all that is needed is a simple method of airflow detection. Designed to be used in both new and existing air ducts, the switch allows airflow detection between 150-750m per minute. Based around a reliable SPDT snap-action micro switch and using a stainless steel air vane, the simple proven mechanical design offers a cost-effective alternative to more complex airflow sensors.
