ZETEC's X-Probe®: Proven technology for fast, "One-Pass" inspections

For nuclear power plant steam generator tubes, ZETEC's X-Probe design uses a combination of bobbin and array technologies to provide quick, simple, and comprehensive "One-Pass" inspections. Inspection strategies using the more efficient X-Probe technique have successfully proven to replace the need for the conventional bobbin with follow up diagnostic MRPC testing approach. On new steam generators, X-Probes are extremely effective for establishing a more conclusive pre-service inspection baseline which can be used for future inspection comparisons and better plant condition monitoring.

The evolution of the eddy current probe has culminated in the advanced X-Probe® array. The X-Probe incorporates multiple bracelets of pancake coils in a dense pattern and takes advantage of sophisticated multiplexing techniques within the head of the probe. Teamed with advanced ZETEC software and instrumentation, the X-Probe delivers a high-speed and high-quality inspection. Already deployed throughout the world, the X-Probe is available in a variety of standard sizes and configurations.
