Sensor for measuring air velocity, measurement range 0.5 - 10 m/s, accuracy 3 % +/- 0.3 m/s. The sensor provides an output signal proportional to the air velocity of 0 - 10 V. Due to the design of the measuring head, the measurement is direction-independent over a wide range. With the mounting flange, a continuous adjustment of the immersion depth into the channel is possible.
