Thermo Anemometer Air velocity and ambient temperature Selection of units HOLD function Minimum and maximum values Automatic average Airflow calculation Airflow calculation with cone Adjustable automatic shut-off Adjustable back light Detection of flow direction (LV107 - LV 110)
LV101 : Proximity sensor LV107/110 : Hall effect sensor
Anemometer : Hall effect sensor (LV 107, LV 110) Rotation of the shaft of the vane powers a circular magnet of 8 poles. A dual Hall effect sensor, placed next to the magnet senses the signals of magnetic field polarity transition. The sensor signal is converted to electrical frequency and is proportional to the air velocity. Signal chronology allows the detection of rotation direction
