1.2.2 Wind Speed
Lambrecht 14577
User Information
When weather condition are are at high wind speeds, the dome of the solar
tracker should close for protecting the sensitive instrument. Thus, wind speed
is one of the parameters which are detemined for protecting the solar tracker.
To increase the reliability of the system, wind speed is provided by two cup
anemometers.

The sensors main advantages are the electromagnetic, non-impact measuring
principle for precise data acquisition and the double supported ball bearing of
the rotation axis. These characteristics assure high reliability, longevity, lower
friction as well as lower abrasion. Fhurthermore there is an automatic heating
element to avoid freezing of the ball bearing.
Maintenance
The Sensor design permits long periods of maintenance-free operation. A
regular visual verification of the sensor as well as a sensor calibration is recom-
mended every two years. In this case remove the cable-plug connection and the
lower nut from the sensors and take it out of the traverse for further services.
