zwickiLine for Flexible Low-Force Testing.
The long-stroke extensometer is designed for tests on extensible plastics, elastomers, films/foils, textiles, leather and similar elastic materials.
It is primarily used for direct extension measurement on specimens with medium and large extensions in tensile and hysteresis tests and also in temperature chambers (using extended sensor arms). The robust mechanical design of the guide assemblies, together with the swiveling knife-edges, ensures safe, reliable operation with specimens prone to whipping such as elastomers.
The fundamental component of the extensometers is a precise guide profile with two weight-compensated measurement carriages. The two attached sensor arms with interchangeable knife edges are suitable for round and flat specimens, as well as notch-sensitive materials. The gripping force of the sensor arms can be adjusted at the specimen.
The sensor arms and knife edges (round/straight) are included in the extensometer scope of supply.
The zwicki long travel extensometer is ready to be attached on the left side of the zwickiLine without the need for complex alignment tasks, and can be retrofitted at any time.
