nabla sensor: the key for trust

The nabla sensor spinner anemometer measures the wind where it makes sense: in front of the rotor at the spinner, where the wind first hits the turbine. Our goal is to provide you with better insights to ensure that your turbines reach their full potential. By measuring all the significant wind parameters, the nabla sensor can help you with wind power optimization, avoid unnecessary loss and even extend the lifetime of your wind turbines.

The nabla sensor technology

The power of the nabla sensor in detail

The nabla sensor uses ultrasonic frequences to measure and calculate all relevant wind parameters. Using the measurement abilities of nabla sensor allow uniquely deep and accurate wind condition insights.

The nabla sensor can help you with:

  • Advanced anemometric system acc IEC61400-12-2 for non perturbated wind measurement
  • Triple or single sensor providing real wind real time (key for high quality data for predictive condition based tools)
  • Lowest uncertainty measurement of wind speed, turbulence, flow inclination and yaw misalignment detection
  • Easy to install
  • Power curve monitoring - detection of true underperformers
  • Rotor acceleration
  • Substitutive of meteo mast
  • Key for WSM - wind sector management refinement - damage mitigation
  • Birds/bats control curtailment downtime reduction
