Air Velocity Sensor

For temperature supervision on the air side of air heating coils in ventilation and air conditioning plants to provide protection against frost.

The sensor measures a point, i.e., it measures the values at a specific location in the flow profile. For recording the mean air velocity in the duct, the sensor’s immersion depth is the key measure. The immersion depth depends on the flow profile. The measurement principle is based on the anemometric measurement principle. The specially developed thin film sensing element of the QVM62.1 is to a big extend independent form the flow direction and is nearly insensitive to any kind of dirt in the airflow.
