Figure 5.3.5. Contents of the aluminium can in case of (a) a WR-SG

and (b) a DWR-MkIII

So far the contents of the aluminium can has not been described. In the WR-SG and

DWR-MkIII 0.9 m and 0.7 m diameter, Figure 5.3.5(a) and (b), the can houses the motion

sensor package and water temperature sensor (optional on WR-SG) at the bottom and partly

inside the mooring eye. The motion sensor package consists of electronics boards, a stabilized

platform with vertical accelerometer, and in case of the MkIII pitch-roll sensors, two horizontal

accelerometers and a three-axial fluxgate compass.

5.3.4 Electronics unit

The electronics unit has been designed from the point of view of modularity. A range of printed

circuit boards each with its own functionality and its own location will fit in the unit. Figure

5.3.6 and 5.3.7 (b) schematically shows the location of the boards; the interconnecting ribbon

cables and coaxial cables are not shown. For a more detailed description of the printed circuit

boards and their functionality see chapter 5.11.2.
