When your turbine control sensors are not working, your turbines are not producing, so we designed our sensors to maximize your turbine availability. Our Hybrid XT technology is based on 20 years of icing climate sensor experience and over 70,000 fielded sensors.

Hybrid XT sensors are engineered with a two-stage contamination protection system to prevent dust, dirt, and water from damaging the bearings. The first level of defense is a fully sealed body that minimizes contamination ingress. Inside, a sealed bearing cartridge system prevents contamination from affecting the bearings. The result: extended bearing life and a recommended maintenance interval of 10 years—meaning fewer maintenance trips to your turbines.

Icing and extreme climates are no challenge for Hybrid XT. The all-metal design conducts heat to the whole anemometer, preventing ice buildup that can affect sensor function. Heat is radiated to the sensor head using a 96W heater that provides ample de-icing power. With Hybrid XT, you can count on worry-free operation in all weather conditions.

Reliability

  • Two-stage contamination protection extends sensor life
    • Fully sealed sensor body minimizes dust, dirt, and water ingress
    • Sealed cartridge bearing system prevents contamination from affecting the bearings
  • Shock-resistant bearing mounting prevents damage caused by rough handling
  • Rugged metal head prevents breakage due to accidental drops or icing
  • Recommended maintenance interval of 10 years eliminates unwanted trips to your turbines

Icing Performance

  • Metal sensor body conducts heat to the whole sensor, preventing ice buildup and increasing turbine availability in icing climates
  • 96W heating element provides ample de-icing power

Anemometer Accuracy

  • Accuracy: +/- (0.3 m/s + 2% of measured value)
  • Starting threshold of < 2m/s
