ECT Tools in the Field - New Tech and Capabilities

ONE REASON EDDY CURRENT IS A POPULAR NDT TECHNIQUE is that it does not require the removal of paint or protective coatings when testing.

ECT also doesn't require you to close down operations to test. Newer technologies, such as EddyFi's Sharck probes, feature tangential eddy current array (TECA) technology and are capable of positioning, measuring, and sizing cracks in carbon steels up to 7mm (0.28").

WITH TECHNOLOGY IMPROVING EACH DAY, ECT continues to provide accurate, non-invasive testing of assets under insulation.

What is Conductivity?

As relates to the ECT capacity, when it comes to conductivity, we are primarily focused on the electrons of the outermost shell of an atom. When an atom has 1-3 electrons in the outer shell, the material will conduct electricity when the atoms are pushed by voltage.

CERTAIN MATERIALS ARE BETTER CONDUCTORS THAN OTHERS. For instance, according to the International Annealed Copper Standard (IACS), copper is the perfect conductor. This is because pure copper has a base value of 100%. A base value of 100% makes it an ideal material that offers zero resistance and, therefore, is a pure conduit for electricity.
