the range from 0.1N to 300kN (0.0225lbf
to 67443lbf). These versatile products
are renowned for ease-of-use, excellent
reliability and precision measurement.
Automation of testing is achieved using
NexygenPlus™ test and control software,
which provides an extensive library of pre-
defined test setups based on international
standards. They can also be used to set up
routine tests or create an advanced multi-
stage test.
An extensive range of standard grips,
probes, fixtures and flexural jigs – with
a variety of sizes, gripping surfaces,
styles and capacities – allow universal
material testing machines to be used in a
wide range of applications. Non-standard
applications can often be
accommodated through
the design of a special
jig or fixture to hold the
particular sample.
For example, a self-
aligning pipe compression
jig has been developed
in order to evaluate the
resistance to collapse
of smooth-walled
or corrugated pipes
manufactured from PVC,
PP and HDPE. Some
specialised applications
may require the material
tester itself to be
modified.
The versatile ‘Plus’ range of high
performance material testing machines,
from Lloyd Instruments, can be used for
a wide variety of compression and tensile
testing on tube and pipe. Typical tests
include ring stiffness, tensile strength and
compressive strength.
The Davenport™ range of polymer test
instruments, such as the MFI series of
melt flow indexers, can be used for the
evaluation of the materials from which tube
and pipe are extruded.
The ‘Plus’ range features 13 universal
single column and twin column materials
testing instruments and tensile testers.
They are designed to make accurate
and repeatable force measurements in
Lloyd Instruments can produce customised
versions of its universal testing machines.
Examples have included a special
extended 100kN machine to provide 2.1m
free movement to perform a ring stiffness
test on pipe.
Lloyd Instruments is a unit of the Ametek
Measurement & Calibration Technologies
Division. Both are part of Ametek Inc, a
New York Stock Exchange-listed company
and a leading global manufacturer of
electronic instruments and electric motors
with annual sales of $2.2 billion.

MoveInspect is based on a camera bar
that is equipped with digital cameras, and
is offered in a number of different versions.
The high-end version is able to conduct
tests at a frequency of 1,000Hz. The
system can also be applied for endurance
testing, as it records data without time limit.
The results of the dynamic measurements
are displayed in a clear and descriptive
manner. They may also be exported
to external analysis software such as
DIADem.
By default, MoveInspect is provided
with a rugged camera body suitable for
industrial requirements (IP65). For dynamic
measurements over large temperature
Aicon 3D Systems is a provider of optical
camera based 3D measurement systems.
The company develops and distributes
systems for inspection and testing, including
car safety and tube inspection.
The company’s MoveInspect optical
measuring system captures 3D dynamic
processes and analyses them with regard
to geometric changes.
Due to a new climate control concept,
MoveInspect is also able to analyse
movements and deformations under
extreme climatic conditions, for example
in environmental chambers. The optical
system replaces mechanical travel sensors,
significantly reducing the setup work.
ranges, Aicon also assembles MoveInspect
cameras with a special body temperature
control.
This is managed by a central unit and
allows for the precise identification of
the geometric changes in a temperature
range between -25°C to +70°C with an
accuracy of up to 10µm. The recorded 3D
movements can be shown in the same
reference system.
The first climate-controlled MoveInspect
system is in use at a German vehicle
manufacturer. The company performs
endurance load tests lasting several days
under different environmental conditions.
