UT Probe MSEB 4 T0°

Hello everyone,
does anyone know the above mentioned probe. We have to repeat a UT performed in the early 1970 years. If You have experiences, data sheets or where we could rent such a probe, please send a mail. Thx in advance, Joerg

The transducer is probably a Krautkramer but I'm not familiar with the "T" designation. The SEB series are dual transducers designed for near surface examination; 4 means it is a 4.0MHz transducer and "M" indicates the transducer element is a smaller dimension then their standard dimension.Krautkramer did have a MSEB 4 H and a SEB 4 H0-deg (Hzero-deg) back then. Today the series is still made by Krautkramer and available from GE Inspection Technologies; their European catalogue, in pdf format, is available from their site. Check-out page 15.

Re: UT Probe MSEB 4 T0°
reply:

This probe is manufactured now by GE Inspection Technologies, Huerth, Germany.
The correct name is MSEB4T0°, product number 54459.
It is a miniature dual-element probe, 4 MHz, for testing machines (immersion technique),
cylindrical housing, 13 mm dia.
The separate transmitter and receiver elements have a roof angle of 0°, i.e. they are in-plane.
The probe is used for testing of thick plates (up to 200 mm).
For ordering , please, contact your local GE IT distributor.

Kind regards

Hello everyone,
thank You all for Your fast and enclosing information.
The probe mentioned was used in contact technique for testing a special austenitic weld.
My local GE Krautkramer dealer informed me it would be ok to use a MSEB4 0 instead. So I will try it...
Thanks again, Joerg

Re: UT Probe MSEB 4 T0°
Hello everyone,
Please tell me the fundamental difference in scanning using a MSEB 4E(0 deg) probe & SEB 4K (0 deg) probe. Or which one is better for tight cracks?

Re: UT Probe MSEB 4 T0°
Reply:

Both probes are straight-beam dual-transducer probes, frequency 4 MHz.
Both probes have roof angles of 0°.

The difference is the size of transducers and, of course, of housings:

SEB 4 0°:
Rectangular transducers, size 6 mm x 20 mm,
focus at 25 mm steel,
recommended working range: 10 mm to 400 mm steel.

MSEB 4 0° (minature):
Rectangular transducers, size 3.5 mm x 10 mm,
focus at 18 mm steel,
Recommended working range: 5 mm to 70 mm steel.

The probes are designed for different working ranges.

Tight cracks will not reflect ultrasonic waves, they are acoustically transparent.
Maybe tip-diffraction will give a (weak) ultrasonic signal from a tight crack.

Best regards
