Features

•     Two-column loading frame with load capacities of 25 kN, 50 kN and 100 kN

•     Double-acting Hydropuls actuator with a high-flow control valve for nominal test speeds up to 6 m/s, 12 m/s or 20 m/s.

•     Extremely high natura) frequency of the test system due to ultra-light grips and mass-optimized attachement of the piezo-electric load cell.

•     Inductive tranducer integrated in the actuator base for measuring piston displacement.

•     LEX 20 high-resolution laser system especially designed for higher accuracy when measuring extremely small specimen elongations in high­speed tests. The response is 100 timen faster than conventional transducers, minimizing phase errors.

•     Working stroke, i. e. acceleration stroke and testing stroke together, amounts to 200 mm.

•     Economic and energy-saving test run.

•     Easy set-up of the test by a remote control unit.

•     Deceleration of piston movement by a hydraulic end cushion.

•     An environmental chamber can be fitted if required.

•     Sophisticated, IBM-compatible per­sonal computer system for automation of test procedure, data aquisition and test evaluation.

•     Intelligent transient recorder for high­speed data acquisition.

•     Easy-to-use software packages written in QuickBASIC*), entitled VHS-TENS and VHS-IMP, specially developed for the requirements of high strain rate tests.

•     Hydropuls Quiektest software GRAPH 56, a comfortable aid for attractive presentation of data and test results.

•     Operating of the computer requires no previous programming knowledge and is restricted to the selection of specific menus with the help of function keys and Input of test parameters.

•     Interactive digital filtering of measured data is possible. The user determines the smoothness of the entire curve or parts of it by single or repeated passen through a second-order filter.

•     Users familiar with QuickBASIC can generate their own test analysis pro­grams, for which the test parameters and test results are accessible at any time.

•     Finally all relevant material properties in accordance with DIN 53455 or DIN 53443 are summarized in a com­prehensive test report and either printed or plotted.

•     All test results are reproducable.
