Method and Apparatus for Measuring Electrical Conductivity

摘要

An apparatus ( 2 ) for measuring electrical conductivity in a material comprises a pair of electrically conducting elements ( 6 ), a first electrical conductor ( 9 ) coupled to the electrically conducting elements, the first electrical conductor coupling a first transformer core ( 10 ) and a second transformer core ( 12 ) to form a first current loop ( 8 ) and a second electrical conductor ( 17 ) of known resistance coupling the second transformer core and a third transformer core ( 14 ) to form a second current loop ( 16 ).
