Wall thickness measurement using the DMS Go+ 1 Introduction
DMS Go+ Edition 4 (05/2014) 1-19
Auto-V (measurement mode AUTO-V)
The function Auto-V enables to measure the wall thick-
ness of uncoated test objects without knowing the ma-
terial's sound velocity. In this function, the sound veloc-
ity is determined simultaneously with the wall thickness
measurement. Uncoated materials can thus be mea
-
sured without an additional calibration and without the
use of reference blocks.
The function Auto-V also uses the probe described with
two pairs of transmitter/receiver elements. One pair of
transmitter/receiver elements calculates the material's
sound velocity by means of a longitudinal sound wave
propagating beneath the surface of the test object and
by means of the known sound path (distance between
transmitter and receiver). At the same time, the second
pair determines the time of flight of the sound pulse in
the test object and uses this value and the material'
sound velocity determined by the first pair to calculate
the wall thickness.
In this way, variations in the sound velocity due to tem-
perature variations or local inhomogeneities within the
material are also included in the wall thickness calcula
-
tion.
The function Auto-V is only available in the version DMS
Go+ TC.
