Ultrasonic Wind Sensor WM80

Extreme cold

Field-proven performance in Arctic conditions. 11 controlled heaters enable ice-free operation, independently verified through MIL-STD 810H anti-icing and de-icing recovery testing under severe icing conditions. The transducers even withstand 50 mm hail balls fired directly at them at 32 m/s.

Vibration endurance

Wind turbines and ships vibrate constantly. WM80 was tested beyond standard IEC 60068 sweeps with long-term endurance runs at typical resonance frequencies per IEC 60945 — zero resonance points found.

Heavy rain

Tested in rainfall up to 200 mm/min. WM80's transducer design clears water naturally while individual heaters prevent condensation. Adaptive signal control maintains accuracy throughout — without relying on hydrophobic coatings that wear off over time.

Corrosion resistance

WM80 has a robust design that fits right in with demanding, naturally corrosive offshore environments. The sensor is built from marine-grade anodized aluminum, designed and tested for C5 (very high) corrosivity environments.

EMC

Tested for electromagnetic immunity and emission compliance in demanding industrial and maritime electrical environments.

HALT

We pushed WM80 to failure on purpose, so we could make it stronger. HALT (highly accelerated lifetime testing) from −70 °C to +85 °C combined with vibrations and shocks from 10G to 50G.

Blowing dust & sand

Independently tested to MIL-STD-810H for blowing dust and sand at temperatures up to 60 °C. WM80 maintained 100% measurement availability throughout, with no data gaps and accurate tracking of reference wind speeds.

DNV type examined

Independently verified by DNV for use on ships and offshore installations. Testing performed according to DNV-CG-0339:2021 and IEC 60945.
