An air flow sensor, also known as a Air velocity sensor. The sensor controls air velocity to a constant value, balance outpressure fluctuations (supply or extract air control), or monitor the flow in air ducts. It primarily is used for modulating fan control in primary plants to set the basic volume flow.
These sensors use a heated wire (or a thin film) and measure the cooling effect of the airflow. The change in resistance of the wire due to cooling is used to calculate the air velocity. They are known for their accuracy and fast response time, making them suitable for a wide range of applications, including HVAC and industrial processes.
Similar to hot wire anemometers, hot film sensors use a thin film resistor to measure air velocity. They are also known for their accuracy and fast response time, and are particularly useful in low velocity applications.
Air Velocity Sensor The Air Velocity Sensor uses the Bernoulli equation and Pitot tube principle to convert pressure into wind speed and air volume output. The host equipped with a standard Pitot tube can measure the flow rate and velocity, as well as temperature and pressure of the air duct. Product Overview Air flow velocity…
