Magnetic distortion areas on Motus
DB1750
•
Areas around parts made of steel. See figure 6. The DB1750 has a float section with internally cross brazed
stainless steel rods that are connected to stainless steel bushings in mooring and lifting eyes. The magnetic
influence from these parts is very low and will not alone affect the sensors internal compass readings.
•
Due to the low magnetic influence from materials in the buoy itself it is normally not necessary to add an
external compass to a Motus DB1750 buoy.
•
NOTE! After external compass has been mounted avoid mounting magnetic objects in the vicinity of the
compass.
