ZMART –
Zwick Modernizationand Retrofit Technology
Modernization packages testXpert
® are available.The decision regarding thepurchase of a new machine
and a modernization primarily
depends on the value and technical
condition of the machine
components to be taken over.
Due to the fact that in addition to
the load frame other components
can be used furthermore, as e.g.:
load cell and extensometer, the
costs for a modernization remainrelatively low compared to the
costs incurring for the purchase
of a new machine.The modernization packagesare composed of the following
components:
•Digital measurement and controlelectronics•Test software With the modernization packages ZMART.KIT
® and ZMART.PRO
® both electro-mechanical andhydraulic materials testing machines of different manufacturers
can be upgraded and brought to
the most recent state-of-the-art.
After a modernization the
guaranteed spare parts supply for
modernized components, the entire
accessory program includingextensometers or specimen grips
and in particular also the most
recent version of the test software testXpert
® •Maintenance-free AC-drives
•Proportional valves or servovalves and hydraulic units for
hydraulic testing machines
