Eddy Current Array

Lightbox ImageOmniscan MX
Eddy current array (ECA) technology provides the ability to electronically drive and read several eddy current sensors positioned side by side in the same probe assembly. Data acquisition is made possible through the use of multiplexing, which avoids mutual inductance between individual coils. The OmniScan® ECA test configuration supports 32 sensor coils (up to 64 with an external multiplexer) working in bridge or transmit-receive mode. The operating frequency ranges from 20 Hz to 6 MHz with the option of using multiple frequencies in the same acquisition.

 


 

Lightbox ImageFlexible Eddy Current Array Probe

Suitable for use in any field, its innovative flexible PCB design enables it to fit any curvature. This new probe can be used to perform a wide range of applications that were previ¬ously difficult to accomplish with eddy current. The cable can be disconnected from the probe to facilitate probe replacement, and different cables can be used to set different modes for the same probe. Our two distinct cable models make it possible to use the same probe with two different coil configurations. Bridge is used for nonferromagnetic materials like alu¬minum and titanium, and reflection is used for ferromagnetic materials such as Duplex and stainless steel. This technology functions as a ready-to-use probe when used with a shape holder, and can also be mounted directly on a scan¬ner using the appropriate holder. In addition, both the probe and the cable are available as off-the-shelf items.
