Electromechanic Test Machine Retrofits

Universal testing systems manufactured by Instron, Zwıck Roell, Satec, MTS, Tinius Olsen, Baldwin, Forney, Adamel Lhomargy, Testometric, Galdabini, Walter Bai, Ibertest, Deltalab, Hounsfıeld, Schenck, Admet, Test Resources, Controls, Hegewald-Peschke, Labortech, Shimadzu, Impact, PTS and others are all capable of being upgraded.

Modernisation of Screw Driven Instruments

Retrofitmach is making retrofit and modernisation of electromechanic material testers. We supply the complete system - starting with the transducer excitation and signal conversion up to the digital drive control, in the appropriate digital control mode. Additionally, we deliver: power amplifiers for the motor, Remote Machine Control, PCs for measured value display, software to do graphical analysis and data acquisition. Existing or new strain transducers are adjusted to the test requirements.

The fields of application are widely spread: Metal, plastics, rubber, foods, concrete, etc. Select the appropriate Software module for your application. A special testing instrument always is a challenge for us. Especially, if it is far beyond the usual testing instruments.

Electronic control system must be chosen by applied test type.

Retrofitmach uses Doli EDC Controllers (Made in Germany) and Doli Test & Motion softwares to upgrade the test machines.

• EDCi10 control systems: 1000 Hz system clock, load and position measurement channels are available.
• EDCi20 control systems : 2500 Hz System clock, generally used for static test systems
• EDCi70, EDCi50 control systems : 10000 Hz System clock, generally used for static and dynamic test systems.

For standard solutions we offer our low-cost Test&Motion Plus Program.

The Intelligent Solution for User Test Applications

A test software should be able to:

1. Display everything I want to

2. Evaluate everything I need to

3. Give everything out the way I like it

DOLI combines these tasks in the Test&Motion Plus Software. Different information is shown in different windows at the same time.

Test&Motion was developed in a modular design. It consists of the basic software containing a simple but adaptable tension/compression test and different modules for almost all kinds of testing applications. The special module Free Programming offers the possibility to design tests individually.

All sorts of signal sources can be displayed. Load, position and strain are standard, but other transducers or calculated results can also be displayed.

Variables are shown as curve in X- or Y-direction or listed digitally. Furtheron, user have the possibility to: change the names of the variables (e.g. load or F), zoom the graphic several times and store remarks within the graphic. If a bigger view of the curve is needed, the graphic window can be drawn up to screen size. Due to the organization in single windows, user do have the possibility, to move important values to a point where user can still see them. T&M is able to process several EDCs in a multiaxial manner. EDCs can be cascaded and - what is even more important - synchronized, resulting in absolute identical signals for all channels. T&M can communicate with several EDCs at the same time.

• Possible X- and Y-axis quantities: load, stress, X-head travel, strain, technical strain, time (from test start), true strain, nominal strain, time and defined signal input determination of five values on the X- or Y-axis, maximum, breach as X- and Y-value. Corresponding determination of values for compression tests.
• Statistic functions: mean value, min/max value, range, median, standard deviation, practical limit of error, aso.
• Display of all data sent by the instrument: load, X-head travel, strain and defined signal input.
