First Class Wind Transmitter
The
First Class wind transmitters are designed to evaluate the location
and capacity of future wind power systems. The anemometer measures
the horizontal component of wind speed and the direction transmitter
detects the horizontal wind direction. The measured value from each
is available as a digital signal at the output.
The rotation of the carbon-fibre reinforced plastic cup star on the
anemometer, is scanned opto-electronically and converted into a square
wave signal. The frequency of this signal is proportional to the number
of rotations. The measured value is available as a digital signal
output.
The light weight, aluminum wind vane runs on ball bearings and through
magnetic coupling to an integrated potentiometer provides a directional
signal that is friction free. Available signals include resistance,
mA, V or digital.
These signals can be transmitted to display instruments, recording
instruments and data loggers as well as to process control systems.
For winter operation the instruments are equipped with electronically
regulated heating, whichguarantees smooth operation of the ball bearings,
and prevents the shaft and slot from icing-up.
