Overview

The First Class Classic wind direction vanes are designed for the acquisition of the horizontal component of the wind direction and have the best accuracy of any vane system with an excellent response in turbulent flows. They are constructed of aluminium for durability and are available in heated and unheated versions.

The sensor is available in a number of variants including digital and analogue outputs. Heated versions are available for use in regions prone to freezing.

The First Class Wind Direction Transmitter has recently undergone an upgrade resulting in a change of part number. The previous series sensors (4.3150.xx.xx) are still available, please contact us for more details.
