Airflow Monitor
The airflow monitor (NC/NO) is designed to indicate the loss of air movement of a fan or filter fan. Comes mounted on a 120x120 mm black plastic grill
The airflow monitor (NC/NO) is designed to indicate the loss of air movement of a fan or filter fan. The contact detects the loss of air movement caused by fan failure or blocked filter media regardless of direction of air. Its simple mechanical operation makes it a viable alternative to electronic monitoring systems.
The product of switching voltage and switching current must not exceed 10 W. The max. voltage and max. current must not be exceeded, not even short-term (voltage/current peaks). The resulting voltage and current peaks of inductive or capacitive loads must be restricted by a contact protection circuit.
