1. Overview
The GS025 is a magnetically encoded
radio anemometer. The wind speed
values are computed from pulses of
magnets inserted in the rotor. This means
that this anemometer has no adjustment
and thus never needs to be calibrated.
Its battery powered electronics gives it an
extended autonomy and the radio
connection allows it to be installed in
remote locations with difficult access.
Both the battery and rotor can be field
serviced without the need for tools.
2. Location
The anemometer location should be on
the same side of the boom as the cabin
mounted display, perpendicular to the
boom, and at the highest point possible.
The wind speed sensor must pivot freely
on the mounting mast at all boom angles.
The wind cups must be fully exposed to
the wind and spin freely at all boom
angles.
There should be a clear and unobstructed
line of sight between the anemometer
sensor and the cabin mounted display
unit.
3. Installation
Weld or screw the mast to the boom at
the selected position.
Note: An iron angle can be used to extend
the reach of the mast to clear the boom
tip.
The U-bolt can be used when retrofitting
the GS025 on an already installed GS020
rod (previous generation anemometer).
Make sure the U-bolt is fully tightened
and add the washer and cotter pin at the
rod tip.
Once the mast is secured in place the
radio anemometer can be inserted on the
pivot and secured in place by the washer
and hairpin.
IMPORTANT! Do not weld in
proximity to LSI sensor/transmitters.
