Wind Direction Sensor

⇓  Description

With the sensor for wind direction the horizontal wind direction is detected over a light wind vane.The dual ball-bearing axle is connected to a timing disk. The timing disc is from a non-contact optical sensorscanned. In the integrated electronic pulses are formed, whose frequency is proportional to wind speed. The recorded data will be ina signal processor pre-processed and in the F-bus protocol to the display device or a further Signal processing units supplied. The distance between the wind sensor and this unit can be on a Twisted pair up to 700m and go up to 3000m with additional repeater modules.

To prevent freezing of the sensor, a heater is installed in the body of the wind sensor. The heating is from about+5° C regulated proportional to the temperature outside

The entire sensor for wind speed is made from corrosion resistant materials and protected with a varnish. Labyrinth sealsand sealing rings prevent moisture from penetrating into the interior of the housing.
