Pipe Mount (PM) Wind Sensor Installation
The Pipe Mount wind sensor is designed for installation on a wind turbine nacelle. The sensor can be installed on top of a pipe or post, using the FT designed adapter. The cable connecting the sensor to the wind turbine controller is run inside the pipe. This helps to ensure a robust setup that completely protects the cable from the external environment.
The alignment of the pipe adapter allows the sensor to be repeatedly fixed without error to the central axis of the turbine.
The sensor has additional heating capacity designed to heat the metal adapter and pipe. This prevents ice from building up on the adapter that could block the air flow through the sensor during heavy icing events. The whole pipe mount system is designed to ensure sufficient heat transfer from the sensor into all the metal work to keep it ice free.
The pipe mount system is made from materials designed to last for up to 25 years in a marine or offshore environment.
Alternatively the FT702LT V22 can be installed on a wind turbine using a flat front sensor, which mounts onto a Bar rather than a pipe.
Inbuilt lightning protection
The sensor, if properly installed, is designed to operate in the most extreme outdoor environments. The FT702LT has inbuilt surge protection, allowing the sensor to be deployed in locations exposed to lightning strikes. The sensor can be located in lightning protection zones 0B, 1 or 2 according to IEC 61400-24 and IEC 62305-1.
A good installation will include surge protection devices inside the controller and appropriately terminated cable screening. The sensor chassis must also have a low impedance connection to ground it to the structure of the nacelle. This can be achieved through the pipe mount adapter.
