X-ray radiography for development of defect-free electrochemical hydrogen meter for sodium systems

Abstract

Radiography has been used to evaluate the quality of electrolyte casting and the alignment of the reference electrode inside the electrochemical hydrogen meter (ECHM). The defect features from the radiography images have been quantified using image processing tools. The methodologies adopted for extracting the defect features and its quantification from image processing have been discussed. The experimental work described in this paper clearly demonstrates that the radiographic technique is a valuable tool to improve the fabrication process and to ensure defect-free electrolyte and proper electrode alignment.
