Conductivity (C)

The RBRcentauro³ C.T.D uses an integrated inductive conductivity sensor which measures the ability of seawater to conduct electric current.

Conductivity measurements are performed using a rugged inductive cell that can be frozen into ice. RBR used computational fluid dynamics (CFD) to optimise its design. The conductivity sensor is streamlined for hydrodynamic flushing through and around it, and does not require a pump, thus ensuring totally silent operation.

While 80% of its volumetric measurements happens inside the cell, they also extend up to 15 cm away and thus may be affected by conductive and non-conductive objects within this distance. RBR calibrates conductivity sensors to account for static objects, such as other sensors or glider body. Conductivity measurements are also temperature compensated.
