Developing a Multiphysics FEA Model of an Inductive Conductivity Sensor

The CTD is a rosette structure which is circular in shape and houses a number of elements. These elements include sensors, water sample bottles, ropes and cables to support the CTD structure. The sensors included in the CTD are not limited to conductivity, temperature and depth, but also include sensors to determine other physical properties. In this research, a model of the CTD sensor designed by RBR will be developed for the purpose of measuring conductivity and determine the nature of the water sample by calculating indirect parameters associated with it. Other parameters such as temperature, pressure and material properties of the sensor are taken into consideration. An objective of this work is also to understand the proximity effect which affects the sensor due to the presence of other known elements near it. COMSOL Multiphysics is utilized to perform simulations for refining the model based on the results.
