Non contact measurement of electrical conductivity of metallic coating
Measuring the electrical conductivity of a metal deposit has always been a difficult task. The reference method is that of Van der Pauw, see https://en.wikipedia.org/wiki/Van_der_Pauw_method. This method requires the installation of the electrodes. This is a delicate operation. Poor contact between the electrodes and the coating under test is a major source of error. We […]
Contactless measurement of the electrical conductivity of metallic coating deposited on plastic
Resistant plastic materials are on the way to replacing metals in a number of applications. The aim is to reduce overall weight and energy consumption, and also to increase resistance to corrosion. Carbon fiber composite material has been used in the aviation industry for a long time. Latest generation aircraft from Airbus and Boeing have […]
Detection of flaws using the eddy current technique
Use of a high resolution probe for detection of flaws on heat exchanger tubes Sciensoria has designed a special probe for the nondestructive testing of tubes. It is a rotative probe with separate excitation and detection coils. The probe features “directional exciting current sheet” that can maximize the sensitivity to flaws. The probe can detect […]

In January 2020, Sciensoria delivered a quality control device for electrical welds on car chassis ordered by the Excelcar platform. This order is part of a research program among the 24 research programs launched in cooperation with PSA Automobiles with the aim of modernizing the design and production of its cars. Increased quality control and […]
Measurement of water level in an immersed container
The “Fish” probe designed by Sciensoria can sense the water level inside a container from the outside. Both the probe and the container are immersed into water. The containers not only contain water, but also filled with small steel nails. A probe is placed outside of the container. It is also immerged in water. It […]
Advantages of the eddy current technique for thickness measurement
Sciensoria’s eddy current thickness measurement technique has many advantages: Single-sided measurement, no mechanical or electrical contact required, capable of measuring on moving targets Good tolerance to air gap variation, or tilting of the probe Good tolerance to changes in target material: automatic compensation of electrical conductivity, magnetic permeability (only for weakly magnetic materials). Small measurement […]
Measurement of the electrical conductivity of poor conductor materials or thin deposits
This nondestructive measurement applies to the following materials: Carbon composite materials (CFRP, carbon fiber reinforced plastic) Graphite Plastics or elastomers plated or doped with metallic particles In the case of carbon composites, electrical conductivity can be an indicator of the proximity between carbon fibers. Electrical conductivity is an essential quality of graphite because this material […]
