Abstract :
Results are reported from an initial evaluation of a novel conductivity sensor that has been incorporated onto a multi-element thick film sensor array designed for soil and water analysis. The new sensor exhibits a more repeatable cell constant of approximately 0.15 cm-1 over a wider range of conductivities compared with conductivity sensor designs previously employed in the sensor array. The new sensor is currently performing very well in an investigation of soil structural properties where its output is being correlated with soil water content in a study of different soil porosities.
