Nomenclature of Probes

Good evening,
I´m studing ultrasonic testing at college and the teacher didn´t know the meaning of the probes letters. Please could someone help me?
The probes are:
MWB45N4
B2S
MB4SN

Regards!

It would seem that these are simply the manufacturers model numbers.

Agree with you TJ, but it would be nice if there was a way to decipher this stuff so that when you want a specific probe you could order what you want.

Talk to a Krautkraemer salesman. These look like KK models to me.
My memory is not that good but I think MWB is a miniature angle beam probably 45 deg with a frequency of 4 Mhz

B2S I think is a straight beam 2 Mhz

MB4 SN 4 Mhz likely a larger one????

MWB is a Krautkramer Minature Angle Probe - 45 / 60 / 70/ 80 etc denotes the angle in steel and the 2 or 4 denotes the frequency- a crystal size of 8 x 9mm is used.
B is the code for a krautkramer 24,5mm dia compression probe
MB is the krautkramer code for a minature compression probe (10mm dia)
The frequency is denoted by the numerals 2, 2,25, 4 etc.

For example a minature 60 degree 4 MHz shear wave transducer will be marked MWB 60-4

Dent McIntyre and Andre Fouche are correct, the requested types are all Krautkramer probes, now GE Sensing & Inspection Technologies.
MWB 45 N4: Miniature angle beam probe, 45 degrees transverse wave in steel, 4 MHz;
B 2 S: Normal beam probe, longitudinal wave, 2 MHz, with soft protection layer;
MB4S: Miniature normal beam probe, longitudinal wave, 4 MHz, with soft protection layer.
You see, there is logic behind this nomenclature.

In NDT practice it is required to have a probe data sheet for each probe you want to use.
(Technical document from the probe's manufacturer) e.g. according to European standard EN 12668-2:
Non-destructive testing – Characterisation and verification of ultrasonic examination equipment – Part 2: Probes

Re: Nomenclature of Probes In Reply to Anderson at 00:17 Jan-24-2009 (Opening).

Hi,
the nomenclature you are listing was born in German.
These probes are manufactured by Krautkramer which is a company of the General Electric holding.
MWB45N4 is a "Mignon" (crystal size 8x9 mm), angled ("Winkel" is "angle" in german language), with Barium as crystal material, at 45° in steel refracted angle, "N" series and 4 MHz of nominal frequency.
B2S is a straight beam probe with Barium as crystal material, and 2 MHz as nominal frequency.
Further explanation could be met at GE website or on the probes data sheets.

Regards

Re: Nomenclature of Probes In Reply to Anderson at 00:17 Jan-24-2009 (Opening).

These are old Krautkraemer probes (from the '70th). The characters mean in german language:

M = Miniatur (miniature),
W = Winkelpruefkopf (angle probe),
B = Bariumtitanat (piezo material = barium titanate),
45 = Winkel (probe angle = 45 degree),
N = Neu (new design, with LEMO plugs, in contrary to 'old' from the '60th),
4 = Frequenz (frequency = 4 MHz),
S = senkrecht (straight = perpendicular to surface).

Probe size of MWB45N4 should be about 10 mm x 12 mm,
Diameter of B2S should be about 24 mm, of MB4SN about 12 mm.

The probes are applicable until today in conjunction with LEMO plug equipped gear (except of B2S; this should be B2SN! The missing 'N' would indicate a historic plug very difficult to obtain today!).

Sorry, I made one mistake:

'S' is not 'Senkrecht (straight)', but, as Udo Schlengermann mentioned two mails earlier,
'S' is 'Schutzschicht (soft protection layer).

As far as I know the first letter - sufix mentioned by any manufacturer after the frequency / angle ( any numbers) mentioned is for the Probe Connectors.

S means Straight Connectors
R means Right Angle connectors

The next letter comes after S or R will the type of connectors

for example: if the connector is BNC , they will mention SB - Straight BNC or RB - Right Angle BNC

Lemo connectors as L and Microdot connectors as M.

The first alphabet of the probe may also confirms the Damping - like high damped, medium damped or low damped etc.,

Each manufacturer have their own identity to market their different types of probes.

Check with KK and download the probe catalogue. Go through the same to get complete details about each probe being used by you.

Probes are equally important to get the right test results for each type of materials.

Good Luck

Simon

Hi
You can very well down load from GE site on probe catalogues. It will give all probe details.
