High Measuring Accuracy and Reproducibility
Maximum accuracy
High (24-bit) resolution and A/D converter with 400 kHz sampling rate for maximum measured-value accuracy combined with large measurement range.
High measured-value rate
Synchronous 2 kHz measured-value logging-rate delivers fast measurement with maximum reproducibility (regardless of number of measurement channels).
AC drives
The powerful maintenance-free AC drive also allows cyclic tests to be performed at maximum speed up to nominal load – with no waiting time between tests.
Adaptive controller
Automatic setting of all control parameters enables exact target-position approach. Changes in specimen properties are compensated for online.
Strain-rate Control
The drive technology’s excellent constant- velocity characteristics and interaction with the sensor technology and adaptive control make it ideal for demanding strain-rate control (e.g. ISO 6892-1, Method A1).
Machine compliance correction
testXpert®II automatically determines the optimum curve, ensuring maximum possible accuracy for travel-measurement and positioning via the crosshead displacement transducer.
