ECT Inspection Systems

TesTex offers an ECT Inspection System, TX 4200. This is based on the eddy current technique, for quick and accurate inspect of the non-ferrous metal tubing from the tube ID; two-frequency system can detect and size ID/OD pitting, baffle cutting, erosion, steam impingement, general wall losses, etc. The system has differential and absolute responses for each frequency. The system also has a built-in reference signal to generate an absolute signal without the use of a reference probe; this model electronics box is coupled with an IBM compatible laptop computer to operate the system through windows-based software. The universal bus system based communication to PC allows sample rates up to 12,000 samples/second/channel. The system has a frequency range from 1 kHz to 1200 kHz; real-time mixing is available for suppression of support/baffle plates. The system may view absolute and differential modes at the same time; electronic board is designed for independent operation to permit easier troubleshooting, repair, and expansion. Additional frequencies can be added by adding additional main circuit boards to the back plane board. Advantages: wide frequency range 1 kHz to 1200 kHz; electronics is less than 5 pounds; system dimensions are H x W x L = 3.5" x 8" x 11"; can operate with a pusher/puller system; windows based software; and 110/220 V operation.
