Structure Test Coils & Probes
Model: Encircling, rectangular, fork, ID and flat coils
ibg's in-house range of encircling, rectangular, fork, inner-diameter and flat coils and probes for eddy-current structure testing, plus custom designs.

About the Structure Test Coils & Probes
Coil selection decides how well a structure test sees the area of interest. ibg designs and manufactures its encircling coils, rectangular coils, fork coils, inner-diameter coils, flat coils and probes in-house, with standard encircling diameters from 5 mm to 300 mm and special designs for specific parts.
Coils remain compatible across ibg instrument generations, so an older instrument can be replaced while the existing coils stay in use. ibg publishes standard sizes and frequency ranges for its rectangular and inner-diameter coils (see technical data).
