Typical Measurement Ranges for ommon Microscan Transducers used !ithPrecision Thickness Gauges

1. These tables are intended as a general guideline only, listing common transducers and typical material thickness ranges only. All thicknessranges are approximate. The actual measurement range in a given case will always depend on instrument setup as well as material properties

such as part geometry, surface condition, and grain structure.

. !aterial is assumed to be at ambient temperature. "n all materials, sound velocity decreases and attenuation increases with temperature, soat elevated temperatures the minimum measurable thicknesses may be slightly lower and the maximum thickness may be significantly lower,especially in plastics.

#. These tables list only some of the most common materials and transducers related to precision gaging applications. There are many more possibilities. "f you need information regarding a thickness application that is not listed here, contact the $anametrics%&'T technical support staff.

Note on Focal Length: Transducer focal length is an important consideration in any immersion application. +ocal lengths listed in the tablesare intended as a point of reference only. ptimum focal length in a given application will be determined by material thickness, sound velocity,

and geometry, as well as the length of the water path used. !ost commonly, +-.(/ and +-1/ transducers are used for thin materials 0metalunder ( mm or )./, plastic under 1) mm or ).4/, with focal length increasing as material thickness increases. 2nfocused 0flat transducersare usually recommended for very thick test pieces, since focuses longer than 3) of the near field length of a given transducer usually have

little practical effect. +or assistance in selecting the optimum focal length for a given application, contact the "S5 technical support group in $aris..

Note on Water Path: !aximum thickness measurement capability in immersion testing is also limited by water path length. This chart assumesthat water path length can be extended as re6uired to meet the condition that round trip transit time in the water path exceeds round triptransit time in the test piece. +or very thick materials, this re6uires use of an immersion tank or special bubblers. 7hen using standard $anametrics%&'T bubblers such as the 8%1)#, 8%1)#A and 8%1)#7, maximum thicknesses will be limited by water path length as follows,regardless of transducer fre6uency9

NOTES

1. !aximum thickness in all cast metals will be highly dependent on grain si:e and surface condition.

. !ay be anisotropic 0sound velocity can vary with orientation.

#. !aximum measurable thickness may be increased through use of extended delay line.

(. !aximum thickness will be dependent on lay up structure and resulting sound scattering.

;. !aximum range in l i6uids is limited by gage echo window. <arger distance can be measured with a flaw detector or pulser=receiver.
