Seac - Model SV8 -Anemometer
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.
Environment
Sensors body is Al-Si aluminium injection moulded and rust preventive painted.
M12 IP65 polarizing connectors are equipped for an easier operation.
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.
