FT742-DM Ultrasonic Wind Sensor

FT742-DM Ultrasonic Wind Sensor by FT Technologies are the world’s toughest wind sensor. It is designed specifically for use with drones and UAV launch and recovery sites and docking stations. With pipe mount for ground station use.

This compact sensor delivers highly accurate and consistent wind speed and direction data in all extreme weather conditions and immune to RF emissions.

The FT742 DM (Direct Mount) is designed to mount on a standard 33.7mm pipe. With a 12-30VDC power supply range, the DM is ideal for permanent, portable or rapidly-deployable weather stations and ground stations used to monitor wind speed and direction conditions for UAV take-off and landing.

Small yet very rugged, it is easy to heat even at low power. With no moving parts to degrade or damage and resistant to shock and vibration, it is easy to transport and will perform consistently time and time again. The hard anodized aluminium body is highly resistant to corrosion, sand, dust, ice, solar radiation, and bird attack. The sensor is sealed to IP66 and IP67 standard.

The small footprint, light weight and ease of integration of our sensors make them ideal for meteorological applications in the defence and aerospace sectors, such as on board unmanned aircraft systems (UAS) and at unmanned aerial vehicle (UAV) ground launch and recovery stations.

FT742 DM Data Sheet

The sensors achieve high accuracy within the measured air speed range of 0-75m/s, and have been used as a pitot tube replacement on fixed-wing UAVs. With full 360° air speed direction measurement, they are ideal for station-keeping and hovering on quad-rotor UAVs, as well as dynamic positioning control in gusty and turbulent environments.
