This Design Idea shows how to use a 63¢ (Q=1) microprocessor reset voltage detector IC in a relay coil drive circuit to greatly reduce the coil’s hold-in current. When asked to estimate the coil ...

A nondestructive testing technology called eddy current array (ECA) is capable of driving numerous eddy current coils that are positioned next to one another in the same probe assembly. In the probe, ...

Development and testing have been completed on a method for measuring external corrosion on steel pipelines using a conformable eddy-current array. The method, developed by Southwest Research ...

MAY I call attention to the most remarkable electrolytic current interrupter due to Dr. A. Wehnelt, of Charlottenburg, which appears to me to be by far the most important improvement that has been ...

For nondestructive testing of magnetic and nonmagnetic materials, the MultiMac multimode eddy current tester works with both encircling/sector test coils and test probes. The Windows-based system can ...
