LFV-E Electrodynamic Test Systems

The LFV-E Test Systems are fluid-free, non-hydraulic system, with force capacities up to 12 kN for fatigue and durability testing.
Models with additional torque drive for tension-torsion application are also available.

These test systems can be used for constant load, monotonic, cyclic (dynamic) swelling or alternating loads in a closed loop control.
As measuring and control channel the axial piston stroke, force / stress or elongation / strain of sample is available. Further external control channels can be connected as physical or virtual (calculated), which are to be used either for monitoring (passive mode) or for operation of system (ative mode).

Electrodynamic Drive Technology
The state-of-the-art fluid-free, non-hydraulic ServoElectric drive mounted on the upper crosshead represents the latest high speed versatile and reliable fatigue rated drive technology, providing backlash-free motion with no fluid compressibility to compromise position accuracy.
The ideal solution for laboratories that desire a compact, space saving, clean and relatively low force unit that requires no environmental
consideration and nearly no maintenance.
