Eddy Current Instrument

NDT Supply has several Eddy current instruments that are solid and reliable for your non-destructive testing. They can be used for the detection of surface cracks and flaws, determine thickness, measure conductivity and sort alloys.   

An Eddy current instrument is manufactured with a straight or angled magnetic probe and an analog or digital meter with a zero reference point. As the magnetic probe is moved over the surface of a conductive material, circulating currents (eddies) of electrons are induced that oppose the externally applied magnetic field from the probe. As a result, surface irregularities interrupt the surface flow of eddy currents and surface cracks and flaws are detected.  An audio alarm may also be activated for additional defect signaling.

 Examples of Eddy Current instruments are the EC5000 models manufactured by Parker Research.  The EC5000 models are small, portable and battery operated. They produce a variable operating frequency range of 55-240 kHz. Weighing less than 2.5 pounds (less the battery charger), the EC5000 models are built with a protective plastic molded case that is dust and moisture resistant. The case lid can be removed for a more convenient access during operation. Smart design features provide a sleek storage area for the battery charger, probe and cable within the plastic molded case. The EC5000 comes complete with probe and cable, battery charger and operating instructions.
