Mechanical switch contact
Versatile fields of application
Small size
Easy to connect

The airflow monitor (NC/NO) is designed to indicate the loss of air movement of a fan or professional 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 industrial monitoring systems.

Application:
The LC 013 is used as a signal contact to monitor professional fans or filter fans in stationary, self-contained Protection Class I enclosures. It can beconnected to monitoring systems with remote control or can directly switch professional alarm devices, such as LED's or signal lamps. Loads with capacities exceeding the indicated switching capacity must be switched via a relay, e.g. our electronic relay SM 010. The airflow monitor with NC contact closes upon loss of air movement, i.e. it indicates fan failure (e.g. red signal lamp). The NO contact closes when fan is in operation and serves as optical function display (e.g. green signal lamp).
