Truedgs Angle-Beam Probes - GE USM 36 Series Technical Reference And Operating Manual

Evaluation according to the DGS method

trueDGS angle-beam probes

®
trueDGS angle-beam probes generate a rotationally
symmetric sound field in the material to be tested like
vertically beaming circular elements.
Because of this, the DGS evaluation using these angle-
beam probes is considerably more accurate than with
the conventional angle-beam probes which contain rect-
angular elements. In the case of conventional angle-
beam probes, it may happen that the reflectors evaluat-
ed according to the DGS method are over-evaluated.
USM 36
The following probes using the trueDGS
are currently available:
● MWB45-2 tD (probe # 35)
● MWB60-2 tD (probe # 36)
● MWB70-2 tD (probe # 37)
● MWB45-4 tD (probe # 38)
● MWB60-4 tD (probe # 39)
● MWB70-4 tD (probe # 40)
These new probes can be selected in the instrument.
The corresponding settings are stored in the instrument
and activated when the probe is selected.
