The 034B monitors wind speed using a three-cup anemometer that 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 data logger pulse count channel, then converted to engineering units (mph, m/s, knots).
Wind direction is sensed with a potentiometer. With the precision excitation voltage from the data logger applied to the potentiometer element, the output signal is an analogue voltage that is directly proportional to the azimuth of the wind direction.
- Designed for continuous, long-term, unattended operation in adverse conditions
- Constructed of lightweight aluminium
The 034B, manufactured by Met One, combines a three-cup anemometer and vane into a single integrated package to measure wind speed and direction. It is cabled for use with our data loggers, and it can provide you with measurements for a variety of applications.
