First Class Wind Speed Transmitter

First Class Wind Speed transmitter accredited to IEC 61400-12-1, for site assessment and power performance of Wind Turbine Generators
Home / Products / First Class Wind Speed Transmitter


High sensitivity mechanical cup anemometer designed for the measurement of the horizontal component of the wind speed. Perfect for site evaluation and the measurement of capacity characteristics of wind power systems. Great for meteorological applications and environmental measurements.

Ideal for site assessment and power performance of Wind Turbine Generators

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.

The sensor characteristics are optimised for dynamic behaviour, even in high turbulence intensities with minimal over-speeding and a low starting value. The sensor is available in a number of variants including digital and analogue outputs. Heated versions are available for use in regions prone to freezing.
