The wind direction transmitter serves for the detection of the horizontal wind direction in the field of meteorology and the technology of environmental protection. Special characteristics: • High level of measuring accuracy and resolution  • High damping ratio at a small delay distance • Low starting threshold  • Magnetic coupling, which is free of hysteresis and wear,   situated between the axis of vane and potentiometer. • Electronic protective circuit for the limiting of current,   and against erroneous connection, with model   4.3150.x0.110 und 4.3150.x0.012 • Easy removal, and mounting when changing the ball bearing An electronically-regulated heating system has been installed with the wind direction sensor for winter operation in order to prevent the ball-bearing and the external rotation parts from freezing. Mode of operation The dynamic characteristics of the wind vane is achieved by the aluminum light-weight construction. The co-action of wind vane and balance weight results in a high damping ratio with small delay distance as excellent characteristic of the complete vane. The axis of the wind vane is running in ball bearings, and is coupled, in contact less magnetic manner, with the axis of the integrated potentiometer. Thus, clearance and friction in the coupling are avoided, and an easy starting is guaranteed. An AC- or DC-voltage of 24 V is intended for the separate supply of the optional heating. In all probability, the heating guarantees a trouble-free function of the Wind Direction Transmitter First Class even under extreme meteorological icing-conditions. The outer parts of the instrument are made of corrosion-resistant anodized aluminum, and stainless steel. Highly effective labyrinth gaskets and O-rings protect the sensitive parts inside the instrument against humidity and dust.
