First Class Advanced Wind Speed Sensor
with digital output


The Advanced First Class sensor is Class A, B and S accredited acc. IEC 61400-12-1 for site assessment and power performance of Wind Turbine Generators.

It is the  only class S 0.5 Anemometer world-wide accredited according IEC 61400-12-1 (2005-12), ISO 17713-1, Measnet.


The First Class Advanced Wind Speed Sensor is a high sensitivity mechanical cup anemometer designed for the measurement of the horizontal component of the wind speed for meteorological applications, environmental measuring technology, site evaluation and the measurement of capacity characteristics of wind power systems.

The sensor meets has defined and optimised dynamic behaviour, even in high turbulence intensities as well as minimal over-speeding and a low starting value. The data is output as a digital signal and can be transmitted to recording instruments, computers, data loggers, process control systems and displays.

The First Class Advanced Wind Speed Sensoris available in heated (model 4.3351.00.000) and unheated versions (model 4.3351.10.000)


*When ordering this sensor on-line please check that you have selected the correct model (the heated version is the slightly more expensive model).
