Definitions of Automated UT, etc.

Do these definitions make sense to you?

Encoder — a device that indicates probe position, thus allowing the position for each data reading to be recorded.

[Note: The above definition would include an encoder wheel and other less conventional tracking devices such as airborne ultrasound encoders.]

Scanner — a device that moves a probe or that guides the motion of a probe.

Manual UT — UT examination where the probe is moved by hand, without encoder or scanner.

Automated UT — Encoded UT examination where the probe movement is preset and computer-controlled.

Semi-automated UT — Encoded UT examination with a scanner that is moved or controlled by hand.

Try:

Semi-automated UT — Encoded UT examination with a PROBE that is moved or controlled by hand.

You have already defined SCANNER as a motion device, not 'ducer.

Dear Sir,

These basic definitions are making perfect sense. I am stating this with the experinece of making a few UT scanners (not for commercial but for internal use) Only thing is we can go on eloborating each definition as per the need and interest.

Please let me know if I am missing something in the question.

Good luck and best wishes

P V SASTRY

Scaner is a device which consist of two elements: data gathering system and convert system. Gathering can be manual or automatic depend on particular situation. But the most importing thing about the scaner is not how to gather the data but how to convert them. The examples of displaying scaning data are digital flow detectors with B-Scan and C-Scan and so on. Sometimes can happen situations that for creating this displays a very complicated gathering data mechanism is used. The idea of B-Scan and C-Scan is very usefull but has a serious simplification. Man can find examples of flow detectors with a scaner which gives more usefull results than B and C-Scan. This flow detectors besides displaying can evaluate testing welds according to different standards. One of that flow detectors is Digital Flow Detector called CUD manufactured by ULTRA Institute.

nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?
