INTRODUCTION
The NRG Systems Hybrid XT (HXT) anemometer is an electrically heated wind speed sensor designed for
wind turbine control and wind resource assessment. The sensor is mounted to the turbine nacelle or
meteorological mast and provides an electrical output signal with frequency proportional to wind speed.
Although the Hybrid XT sensors can be used for meteorological work, this manual is specific to turbine
control applications. However, there should be little difficulty in adapting these sensors for
meteorological applications.
The Hybrid XT is rugged enough to accurately measure wind speed in excess of 70m/s (156 mph), yet its
relatively low moment of inertia permits it to respond rapidly to gusts and lulls. It is built with corrosion
resistant materials and finishes, and is sealed against wind-driven rain and dust.
The Hybrid XT sensor line has a captive mounting system with integral connector that allows quick and
easy changing of the sensor. There are only three internal components (electronics module, heater
assembly and bearing assembly) for ease of maintenance. The Hybrid XT also has a spare label pocket
for a customer-supplied identification label.
