Ship version*
(short wind vane,
reinforced cup star, special
ball bearing)
* Comb. Wind transmitters for heavy mechanical load, for ex. on ships, wind power plants or the like.
The combined wind transmitters are shipped in semi-mounted state, in order to avoid transport
damages and to keep the package small.
The following parts are included in delivery:
1 x combined wind transmitter, pre-mounted
1 x cup star
1 x wind vane
1 x connecting plug
1 x Instruction
2 Application
The combined wind transmitter serves for the acquisition of the horizontal components of the wind
speed and the wind direction. All measuring values are available at the outputs analogue signals.
They can be output to THIES-display instruments, and systems or for further processing.
For winter operation the instruments are equipped with an electronically regulated heating in order
to guarantee a smooth running of the ball bearings, and to avoid ice-formation at the slot of the
outer rotation parts. The electrical supply of wind transmitter heating is carried out, for ex., by our
power supply unit, order-no. 9.3388.00.000.

Construction and Mode of Operation
The housing, cup star and wind vane are made of aluminum, die the surfaces are anodized. The
bow consists of stainless steel. Labyrinth seals and o-rings protect the sensitive internal parts from
precipitation. The instrument is designed for mounting to a mast tube; the electrical plug connection
is situated in the transmitter shaft.
A low-inertia light-metal cup star (in ball bearings) is set into rotation by the wind. A pulse frequency
is available at the output through the opto-electronic revolution-scanning.
The wind direction is acquired by means of an inertia-free wind vane. The axis of the wind vane is
running in ball bearings and carries a diametrically magnetized magnet at the inner end. The angle
position of the axis is scanned contact-free by a TMR- Sensor (Tunnel Magneto Resistance)
through the position of the magnet field. As signal this sensor outputs two cosine- and sinus-
depending voltages.
