F T 722- D M5 0 ( DIRECT MOUNT) A COU S T I C R ES O N A N C E W IN D SE NSOR The FT742-DM50 wind sensor fits directly onto a 47.9 to 50.2mm OD pipe and reads wind speeds up to 50m/s. For ease of alignment, it can be fitted using our special FT039 alignment collar and FT040/041 alignment tools. With superior corrosion resistance and lightning protection, the DM50 has been specifically designed for wind turbine control. The hard anodised aluminium body is highly resistant to corrosion, sand, dust, ice, solar radiation and bird attack. The sensor is sealed to IP66, IP67 and IPX6K standard. Small yet very rugged, it is designed to last for up to 20 years, even in an offshore environment. With no moving parts to degrade or damage and resistant to shock and vibration, it is easy to transport and can be used to upgrade and retrofit older turbines. DI MENSION S A. Sensor height C.
