MANKOWSKI, R R. Design of a single-probe mechanical anemometer for measuring horizontal wind components and direction. R&D j. (Matieland, Online) [online]. 1992, vol.8, pp.8-20. ISSN 2309-8988.

The work described here sets out the dynamic theory behind the design of a single-probe mechanical anemometer. The probe is the upper extension of a compound pendulum exposed to the wind, wind speed and direction being obtained from the angle of tilt and azimuth angle the pendulum subtends during dynamic equilibrium conditions. A contactless inductor type transducer is used as the positional indicator the output of which varies linearly with winds peed and direction. The uniqueness of the design allows for an extraordinary wide range of sensitivity and working speeds without major mechanical changes. Experimental evidence gained from wind tunnel tests and a field test clearly indicate further improvements are possible and will depend to a large extent on the realization of a reduced scale of the original model.
