A PLUS for the USLT 2000

The software program RTM is an additio-

nal module for the ultrasonic test system

USLT 2000 that can be easily installed

as an optional „Plug-In“. This additional

software extends the range of functions

of the USLT 2000; new ﬁelds of applica-

tion are opened up.

The RTM module (Resonance Thickness

Measurement) is used for carrying out a

precision thickness measurement on very

thin objects.

Wall thicknesses are usually determined

on the basis of the time of ﬂight of a

sound pulse; in this connection, the

wall thickness corresponds to half of the

sound path (pulse-echo method).

However, this method only works if the

wall thickness is larger than the wave-

length.

Module RTM

...for precision thickness measurements on thin metal sheets and layers

The RTM method is used in particular

if the wall thickness to be measured is

smaller than the ultrasonic wavelength:

• because higher sound frequencies are

not possible for reasons of instrument

technology

• because low operating frequencies

and consequently large wavelengths

have to be used due to high sound

attenuation

• when low frequencies have to be

selected to carry out a measurement

on heavily corroded sheet metal.

The applications ...

• in sheet metal working:

The RTM module makes precision

thickness measurements on thin sheet

metal and layer possible, which means

for example by means of a 20 MHz

probe on sheet metal between 0.15 mm

and 1.5 mm at an accuracy of ± 5 µm.

• in shipbuilding:

In yacht building, wall thickness

measurements can be carried out

for example on glass-ﬁber reinforced

components.

• in offshore operations:

Even the checking of wall thicknesses

on heavily corroded components in off-

shore operations is no longer a problem.
