Instrument for measuring ratio of component in composite material

Abstract

Abstract PURPOSE: To accurately measure the ratio of components in composite material by arranging a plurality of positive and negative electrodes on substantially equal plane and guard electrodes for preventing electric line of force leaked except for facing electrodes at essential parts. CONSTITUTION: Positive and negative electrodes 6 and 7 are alternatively arranged on a plane of measuring electrodes, and guard electrodes 8 are arranged around the electrodes 6 and 7. Guard electrodes 9 are also arranged on the top surface of the measuring electrodes and grounded to shut off external noise. The ratio of components in the composite material is measured by making the probe contact with the surface of testpiece. COPYRIGHT: (C)1980,JPO&Japio
