Volu probe fi ss fan inlet airflow traverse probes.
Duct mounted air flow sensor.
An air switch senses positive negative or differential air pressure and actuates an internal switch.
Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans.
This provides rapid response to the air or gas flow and amount and direction delivering a proportional output voltage.

It will cause your sensaphone to activate an alarm when the airflow reaches a set threshold.
Belimo offers a broad range of air duct sensors covering all standard measurement values.
Air stream sampling is accomplished by sampling tubes that penetrate and traverse either the supply or return air ducts.
This air flow transmitter registers the airflow speed according to a thermal principle based on the fact that the cooling action of air increases with airspeed.
