Abstract
A sensor for measuring conductivity of a fluid containing dissolved ions, particularly for measuring conductivity of salt water, features a cylindrical tube () of poorly conductive material such as glass, a first electrode (A) and a second electrode (B) inside the tube, connected together () to maintain a common electrical potential, a first transformer () concentrically arranged around the tube () to drive current through the fluid in the tube, and a second transformer () arranged to sense a value of the current flowing in the fluid, and a digital processing circuit () coupled to receive an output signal of the second transformer, and to derive therefrom a value representing the conductivity of the fluid. The sensor is adapted to be towed behind a research ship, or to be deployed on an autonomous underwater vehicle (AUV) or the like. Current signals are preferably processed by digital switching measurement technology (dMST).
