Know your gear
This air flow transmitter registers the airflow speed, according to a thermal principal, based on the fact, that the cooling action of air increases with airspeed. Used with any Sensaphone, that will accept a 4-20 mA input signal, the device will provide real-time data and will cause your Sensaphone to activate an alarm, when the airflow reaches a set threshold. This is especially useful for monitoring air conditioning in ducts.
