Standard testing machines (500 N up to 600 kN)
A wide spectrum of standard testing machines in form of table-top
machines and free-standing machines are covered by a test
range from 500 N up to 600 kN. These electromechanical machines
can be universally used in reseach, gauging and quality
control for production of metals, plastic, textiles, construction
materials, wood, ceramics and many others. TIRA WPM testing
machines can be armed according to the wishes of the customers
by the modular structure of the system at any time. The machines
are effective and work reliable and well-established.
A user-friendly and clear operation by the graphic operating
interface "WINDOWS" are a feature of our machines.
LOAD FRAMES
You can see the required load frame configurations in the chart
opposite. Precision construction with guide pillars and recirculating
ball spindles free from play guarantee a high degree of
rigidity and tensile, compression and alternating load testing in a
lower test space. As an option, all models can be supplied with
a second upper test space. The large test area width and height
can be expanded on your request.
This makes it able to test highly ductile specimen as well as complete
sub-assemblies including the fitting of a large variety of
accessories such as force, path and elongation sensors as well as
temperature chambers and tube furnace. For special tests of particular
sub-assemblies, we can supply a number of special designs
of horizontal, extended and extra wide load frames eg. for
pallets and packaging materials. All load frames can be fitted
with corresponding operator protection, depending on individual
test requirements.

DRIVE
The electromechanical drive of TIRA WPM
machines allows precise loading of the specimen
in conjunction with the corresponding
load frames. The test piece can be loaded adjusted
for the path, force and expansion with
aid of digital regulation. In this case the target
value and control parameter can be adapted
over a wide spectrum both manually and software-aided
to the particular test requirements.
It is also possible to change the type of control
during the tests without problems. The crosshead
speed range quoted for the individual basic
models is only a standard case; any other
range can also be supplied. Practically, any
speed from vT = 0 up to vT = max. can be
used.
LOAD CELLS
We use exclusively precision wire strain gauge
DMS-sensors for all measurements in tensile,
compression and bending tests. Sensors particularly
stable against lateral force are employed
for loads with increased side force. In
addition, we can adapt individual customer
load cells to our measurement systems.
Standard testing machines
(600 up to 5000 kN)
Standard testing machines more than 600 kN
are supplied with a hydraulic drive. The test
area and the piston stroke are formed according
to your requirements. A force, path and
elongation regulation are made possible by the
supply of appropriate transducers and an electronic
drived hydraulic valve. The use of these
machines allows the tensile, compression and
bending tests of specimen as well as tests of
components in the static and low-frequency
range up to 50 Hz.

Measurement and control technology
Our machines are equipped with a powerful and intelligent
mesurement and control electronic which ensures a precise test
control and high measurement accuracy.
Two operating methods are provided to control the test machine:
• Stand-alone-Mode for simple tests
• PC-controlled for higher demands and universal applications
The measurement and control electronics are installed in a separate
housing on the front of which a screen digitally displays the
force and path measurement variables as well as buttons to operate
the test machine and enter the test parameters. We can provide
an on-table unit and a control circuitry cabinet for the PCcontrolled
mode.
Two different configurations for the varying
requirements are offered (see the chart
above)
We offer a digital measurement and control
unit for servo-hydraulic test machines for
the high-dynamic tests. (see page 14)

As an option, the control can be equipped with:
TF-Module: carrier amplifier
to connect an analog sensor
INC-Module: two incremental sensor input
man. keyboard: to control the testing machine
(electromechanical machines)
or the test cylinder
(hydraulic machines)

Software
In the PC-mode, we offer a modern and simple to use software
package under MICROSOFT WINDOWS. Our continually updated
software liabry contains a large selection of application
programs (eg. acc. to DIN, EN, ASTM, ISO) and individual customer
tests. The software can be supplied in many different languages
like English, French, Spanish, Russian or Czech.
The main menu window clearly shows the test data diagram,
numerical test results and statistics in a tabular format. All software
functions can be easily and quickly accessed via menus and
a tool (set-up, test configuration, test protocol and so on).
An online help menu explains all functions and gives detailed
advice about individual test standards.
The software package TIRAscript makes it possible to define by
the user himself how a test should be done and which results have
to be determined. In this way, you can realise each test assignment
by yourself with our testing machine.
TIRAscript consists of the following components:
• controlling of the test according to any test procedure in permanent,
swelling or changing load with determination of
force, path, elongation or other measured quantities for the
calculation of parameters which have to define.
• calculation of parameters after the test with any arithmetical
combination, fixing the output value and presentation of the
test results in a current test graph.
