Ultrasonic anemometers

Compared to traditional ultrasonic anemometers, FT sensors deliver a 40 dB stronger signal, giving them an edge in extreme weather, high vibration, and acoustically noisy applications. FT Technologies designs and manufactures high-quality, high-performance wind sensors in the UK and exports them for industrial applications worldwide.

No maintenance

Compact, solid-state wind sensors with no moving parts to fix or replace. This means that once installed, you can trust that you will receive consistent, reliable data exactly when you need it.

Certification

ISO 9227 (2006)

Corrosion Resistant: Tested to category C5-M High of BS EN ISO 12944 (1998) in a neutral salt spray atmosphere for 1440 hours.

View certificate
MIL-STD-810G

Anti-Icing Test: With the heater switched on, the sensor was exposed to freezing rain in an airflow of 15m/s at -15°C. Even when 37mm of ice had built up on the test bar the sensor itself remained ice-free. De-Icing Test: The sensor was ice-free in under 5 minutes.

WHAT OUR CUSTOMERS SAY

The FT205, mounted on our drone, worked perfectly in real fire situations. The data it produced proved critically important to the emergency services as they were able to predict the spread of the blaze during the night.

Javier Prada Delgado

After hearing about the reliable performance of the FT sensor and then holding it in my hand and feeling the difference in weight and size, I was convinced. The weather can throw anything at us now. Changing to the FT sensor has made it possible to keep these turbines running, even in our coldest winter conditions.

Guy Le Blanc

Minnesota Wind Farm

The FT wind sensor was the only one to survive – the other two ultrasonic wind sensors were so badly damaged they stopped working altogether. The FT sensor, however, remained ice-free and continued giving measurements, and that was one of the worst icing events we have ever seen at the observatory.
