Description

The QVM62.1 records the air velocity as a measured value and converts it to an active
DC 0…10 V or 4…20 mA output signal.
Three measuring ranges are available:
0…5 m/s, 0…10 m/s, and 0…15 m/s.
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.
