Conducsens™ – A Multi-Parameter Testing Tool for Flat and Curved Geometries
Conducsens™ – A Multi-Parameter Testing Tool for Flat and Curved Geometries
Conducsens™ is an expert system for non-destructive eddy current testing. It provides all the essential functions needed for this type of inspection, including:
-
Measurement of sensor impedance in single- or multi-frequency mode. The frequency range depends on the model of the impedance analyzer used. Compatible models include the Hioki IM3570, IM3536, IM3533-01, Keysight 4980A, and Hewlett-Packard HP4192A.
-
Simulation of sensor impedance.
-
Impedance inversion in single- and multi-frequency modes. This process enables the calculation of the desired parameters from the impedance values measured by the impedance analyzer.
Conducsens™ is often used for highly challenging applications, including:
-
Thickness measurement of enclosed metal objects made from various metals, which are not predetermined. In this case, both the thickness and electrical conductivity of the material are measured simultaneously.
-
Thickness measurement of thin nickel sheets, a magnetic material.
-
Thickness measurement of turbine components manufactured using 3D printing.
-
Electrical conductivity measurement of low-conductivity materials, such as graphite or carbon composites.
The Conducsens™ system has been used by prestigious companies, including:
-
Alstom Power (now General Electric Power) for measuring the wall thickness of 3D-printed turbine blades.
-
Airbus Innovation Works for measuring the electrical conductivity of carbon fiber reinforced plastic (CFRP – carbon composite).
-
Surys for measuring the thickness of high-precision electro-deposited nickel plates.
-
Schneider Electric for sorting magnetic stainless steels.
-
Mahle, in particular, for measuring the wall thickness of car air-conditioner pistons.
Two Conducsens™ systems from Sciensoria inspected over one million pistons within six months, ensuring a wall thickness consistency of 0.01 mm on a standard 1.5 mm thickness.
The Conducsens™ system is an ideal complement to ultrasonic thickness gauges. While ultrasonic instruments excel at measuring thick walls, their accuracy decreases as the wall thickness decreases. This is because, in thin walls, the echo returns very quickly after reaching the opposite surface, making it difficult for the electronics to measure the time with high precision.
In contrast, the eddy current method performs exceptionally well for thin walls, though its accuracy decreases as wall thickness increases. As a result, both methods are highly complementary and can be used together for optimal measurement performance.
The measurement range of the eddy current method spans from several micrometers (µm) to approximately 10 mm, depending on the material’s electrical conductivity. For example, in the case of aluminum, the typical measurement range is 10 µm to 3 mm.
