| The surface of drawn wire and tubing
must be free of cracks, holes and other material defects as even
small surface defects can lead to defective end products, critical
in items such as surgical instruments. Eddy current testing is
extremely successful in detecting surface defects at various stages
during the production process. For the best test results, encircling
testing is used together with rotational
testing. Eddy current probe types Encircling inspection. A robust, simple encircling coil surrounds the test piece and detects a multitude of defects in ferrous (with magnetization) and nonferrous materials. Rotational testing. The eddy current probes of the rotating system spin around the test piece as it moves through the equipment. The rotating system is particularly sensitive to longitudinal defects and excellent for large tube diameters (up to 130mm (5 1/8"). PRUFTECHNIK's series of rotating systems was designed for easy operation and maintenance, and with the raw industrial environment in mind. Eddy current test
