Kappa LA dead weight

Kappa LA with Dead Weight

This Kappa LA lever arm testing machine maintains constant load application via the gravity force of the dead weights and the patented lever arm.

  • Wear-free flexible joints provide high-quality lever arm mounting and ensure Class 1 measurement accuracy in a measurement range from 1 to 100% of nominal force as per ISO 7500-2.
  • No friction, no wear and constant force application.
  • Maximum precision, maximum reliability and long service life
  • Controlled lead screw drive maintains the lever-arm in a horizontal position during the test
  • Axiality compensating links in the load axis
Kappa LA Spring

Kappa LA with Pretensioned Spring

This Kappa LA lever arm testing machine maintains constant load application via a pretensioned spring and the patented lever arm mounting.

  • Wear-free flexible joints provide high-quality lever arm mounting and ensure Class 1 measurement accuracy in a measurement range from 1–100% of nominal force as per ISO 7500-1, while eliminating knife-edge problems during the entire service life of the machine.
  • No friction, no wear, and constant force application
  • Maximum precision, maximum reliability and a long service life
  • Precise load and strain control
  • Controlled lead screw drive maintains the lever arm in a horizontal position during the test
  • Axiality compensating links in the load axis

Creep and fatigue testing at high temperature

Increases in performance in high-performance applications can often only be achieved through increased thermal and mechanical loads on the components. However, in the case of many materials this requirements specification leads to failure (through creep and/or fatigue). For example, many metals exhibit structural changes under load, starting at 30 to 40% of their melting temperature, which lead to irreversible plastic deformation. The Kappa creep test machines from ZwickRoell are optimally suited to determine the maximum service life of components under this type of load.
