2012 Newest LC 013/LCF 013 Airflow Monitor Meter
1. Mechanical switch contact
2. Versatile fields of application
3. Small size
4. Easy to connect
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.
