| | | Test software testXpert® Range of application testXpert® is the universal Zwick test software for materials, component, and functional testing. It's application range goes from Zwick materials industrial testing machines (for tensile, compression, flexure and functional testing) to hardness testers manufacturer, pendulum impact testers, extrusion plastometers, automated test systems, etc. right up to the refurbishment of testing machines of a variety of makes and models. Duties and functions The essential fields of use of testXpert® are: • verification and re-equipping the test machine • preparation of the test or test series • performance of the test • evaluation and documentation • data management • quality management and • data exchange between testXpert® and other applications (Word, Excel etc.) testXpert® supports the user for all tasks with software wizards and editors, explanatory pictures and video sequences, situation-specific user tips, warnings, error messages and online help. Future-oriented concept The testXpert® test software uses the special properties of the object-oriented programming with respect to a clear grouping in tasks and functions. Structure and contents are determined by the Zwick application and software know-how. The testXpert ® concept is therefore a guarantee for highest flexibility, functional safety as well as simple usability. | | |
| | | Electro-mechanical drive systems The basis of all electro-mechanical drive systems are backlash-free and low-friction ball screws and digitally controlled drive systems (load frames for test loads of more than 600 kN are equipped with servo-hydraulic or hybrid drives). Together with the digital measurement and control system they have the following advantages: • Extremely high, stepless speed range • Very low speeds adjustable (from about 0.001 mm/min on) • High-precision and exactly reproducible positions and speeds The testing machines designed with single-column load frames (zwicki and BasicLine) are equipped with low-cost d.c. drives, all the other ones with particularly low-inertia, brushless three-phase drives. | | Strain gauge load cells are available for precise force measurements from 0.04 N onwards. Together with the digital measurement electronics they have the following advantages: • Automatic recognition of the load cell's serial number • Automatic recognition of the setting and calibration parameters • Overload protection • Automatic zero and sensitivity alignment • Compensation of temperature fluctuations • High measuring frequency • High test data resolution • Accuracy of 1% of the displayed value (1% error limit) from 1/500 and 0.5% of the displayed value on 1/100 of the nominal load. (Type II load cell, F > 500N) • Manufacturer's test certificate to give proof of the works calibration Load cell with one or two sided mounting stud and self-identifying sensor plugs are available for nominal load capacities from 10 N on. | | |
