Anemometer SV9
Composed of 3 cups conical shaped injected on a stainless steel shaft.
The transducer consist on one pair led & phototransistor which provides a pulse output with frequency proportional to wind speed
Combined with high performance shielded bearings ensure excellent linearity, over the whole range of measure and high reliability on different temperature-humidity conditions. Low moment of inertia, low-threshold, fast response and low distance constant are guaranteed.
The variety of outputs suit most data loggers on market.
Wind vane SD9
Consist of one aluminium and steel wind vane attached to a shaft that incorporates a diametric magnet that actuates on a rotary position sensor giving an output equivalent to the direction indicated by the wind vane.
As there is not mechanical contact, there is not friction and so a high life expectancy
A low-threshold and fast response are guaranteed.
The variety of outputs suit most data loggers on market.
Environment
Corrosion and environmental degradation resistance is guaranteed by the UV-proof plastic body.
Bearings
Both sensors are composed of stainless steel, shielded bearings, which give them excellent dynamic characteristic with very low mechanical friction.
Heating
Optionally both sensors could be provided of internal heating system, in order to avoid bearings and shaft freezing. It is strongly recommended in cold climates.
