Criterion CR-11 Eddy Current Crack and Flaw Test Instrument

The Criterion CR-11 is a single-channel eddy current crack test instrument that detects cracks and surface flaws in components and in bar, tube and wire stock in real time on the production line. An excellent signal-to-noise ratio catches the smallest flaws, and adjustable alarm shapes reduce false rejects. It is built for 24/7 manufacturing.

What it does for your operation

• 100% inspection before shipment: every part is checked at line speed, reducing the risk of cracked parts reaching customers and warranty cost.
• Fewer false rejects: ellipse, square, hexagon or auto alarm shapes keep good parts out of the scrap bin.
• The smallest flaws: a high signal-to-noise ratio reveals fine fatigue and grinding cracks.
• Improve with data: a multi-view strip chart helps review test data and optimise flaw responses; screen captures go to a USB stick.
• Ready for automation: TCP/IP, discrete industrial I/O and optional RS232 connect to robots, conveyors and sorting systems.
