ELECTRICAL CONDUCTIVITY SENSOR MEASURING AGAINST DIRECT CURRENT OF LIQUID SUBSTANCES WITH LOW SPECIFIC ELECTRICAL CONDUCTIVITY

摘要

FIELD: electricity.SUBSTANCE: sensor comprises two electrodes rigidly interconnected through a dielectric spacer. At that one (the first) electrode is made as a cylinder with a radius Rand height hwith N round cylindrical openings with a radius R; symmetry axes of the openings are parallel to the cylinder rotation axis. The second electrode is made as N round cylindrical pins with a radius r (r
