The Classic Wind Direction Transmitter is designed for applications where accuracy and reliability are paramount.

The Classic Wind Direction Transmitter measures the horizontal wind direction with an analogue output. This can be transmitted to a display, recording instrument, data logger or process control system. For winter operation the sensor is equipped with electronically regulated heating. This guarantees the smooth running of the ball bearings and to avoid ice formation on the body.

The housing is made of anodised aluminium for good corrosion resistance and long life. Labyrinth seals and O-rings protect the sensitive internal parts from precipitation. The instrument is designed for mounting to a mast tube and the electrical plug connection is situated in the transmitter shaft.
