Near-field array (NFA) is the multiplexed evolution of near-field testing (NFT). Thanks to its sizing capabilities, it is an excellent alternative to IRIS in fin-fan air coolers and ferromagnetic heat exchanger tubing.
Pulsed eddy current (PEC) is an advanced electromagnetic inspection technology used in detecting flaws and corrosion in ferrous materials typically hidden under layers of coating, fireproofing, or insulation.
Tangential eddy current array (TECA) is an advanced electromagnetic inspection technology that uses ECA to introduce alternating currents into the surface of the component under test to detect and size surface-breaking cracks. Here’s what you should know.
