Technical Description

The 034B monitors wind speed using a three-cup anemomettehart contains a sealed magnetic reed switch. Rotation of the cup wheel produces a pulse that is directly proportional to wind speed. The frequency of the pulse is measured by the datalogger pulse count channel, then converted to engineering units (mph, m/s, knots).

Wind direction is sensed with a potentiomete With the precision excitation voltage from the datalogger applied to the potentiometer elementth,e output signal is an analog voltage that is directly proportional to the azimuth of the wind direction.
