If a measurement of traverse movements is insufficient even with given compensation of minor machine-deformations, adaptable transducers, customarily named extensometer, are directly necessary at the probe or between chuck heads or pressure plates.
With mechanical extensometer we distinguish between:
- Clamp-on-extensometer for small strains
- Long-Way-extensometer on separate stands
- Semi- and fully-automatic extensometer with one or two measuring ranges
With a wide range of accessory our optical Video-extensometer are applicable for many, even robotised, applications.
