SERVO HYDRAULIC DYNAMIC TESTERS MODERNISATION

Modernisation and maintaining the value of dynamic testers.

Unaxial or multiaxial dynamic testers can be modernised with  Doli EDCi50 or Doli EDCi70 this controllers was conceived for dynamic testers, especially.

The EDC's has the best qualifications due to:

•             bumpless transfer, automatic amplitude control

•             fast measured value transfer, variable bus-conception

•             EDCs that can be synchronized among themselves

•             fast communication with the PC

Retrofitmach will deliver the new electronics and if needed all other necessary parts such as hoses, valves, units, filters aso.

•             Your cylinder has a problem? - We can repair it or deliver a new one at best quality.

•             You have multiaxial test tasks? - Via the synchronization of the EDCis an absolute simultaneous measured values acquisition of all connected transducers within the tied system is guaranteed. 

Application

Application: biaxial test loads, tension/torsion-tests, tension/torsion-internal pressure tests etc.

SOFTWARE SYSTEM INTEGRATION

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 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 cascade 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.

Data Export

Users have several possibilities to export data. For example user may export: in an ASCII-File, in an EXCEL-File, via a serial interface or in an ECLIPSE-File. In case user want to export user data please do as follows.

• With “End of Test” choice, the users can choose easily end of test how and when. The option allows user to protect the machine. In addition, the option has automatic fracture recognition.
