HR II MASTHEAD UNIT*

HR WIND UNIT The wind sensor “HR” is highly accurate for both angle and speed measurements: less than 1° for wind angle and less than 1% for wind speed linearity. It measures wind angle through360° and its sensitivity allows wind speed measurement below 2 knots. It is easy to install on the mast head. An offset value adjusts the alignment to the boats centreline. This offset is usually required as the mechanical alignment achieved during installation is not accurate enough.The wind angle value is dependent on getting the alignment correct first. This sensor is available with a long vertical arm (see Carbowind).
