CIRCOGRAPH CI

Compact inline eddy current inspection for longitudinal surface defects on bright products

Compact, intuitive and reliable surface inspection. The CIRCOGRAPH CI is a compact eddy current inspection system for the non-destructive detection of longitudinal surface defects on bright products such as tubes, bars and wire. Designed for production lines with moderate inspection speeds, it combines reliable defect detection with intuitive operation in a compact, space-saving system.

Equipped with two inspection channels, continuously adjustable test frequencies from 30 kHz to 1 MHz and a wide range of rotating sensor heads, the CIRCOGRAPH CI can be adapted to a variety of applications and product dimensions. Surface-breaking defects from approximately 30 μm can be detected reliably and contactlessly.

The integrated operator interface with Turn & Push control enables fast setup and simple operation directly at the instrument. Ethernet connectivity and configurable I/O interfaces allow seamless integration into existing production lines while supporting quality documentation and data exchange with higher-level systems.
