A basic measuring probe for displacement determination.
LINE
An elementary measuring probe for strain and length determination.
TRANS LINE
Offers a multi-positional transversal measurement with averaged and max/min width functions.
EXTREME LINE
Probe for axial neck detection. Provides improved E-modulus reading and eliminates invalid tests caused by failure outside the gauge length area.
BEND LINE
A probe designed for bending tests. Measures strain over a curved shape and enables to visualize the real-time strain distribution.
TORSION LINE
Enables dual position angular twist and strain measurement.
LINE STRAIN DISTRIBUTION
Provides a colorful strain visualization feature during real-time measurement.
CRACK PROBE
Measures crack length during static or dynamic tests.
DIC AREA
A full-field probe for strain and displacement distribution mapping.
ROD LINE
Designed for rebar measurement, it compensates for the detachment of the oxide layer during testing. Includes the axial neck detection feature.
A – AXIAL STRAIN
Allows for measurement of axial strain in real-time. In addition to the elementary measuring probes such as Point probe and Line probe, the Alpha Axial Strain measurement module includes the Extreme Line probe that divides the length of the specimen into multiple precisely defined gauge segments and detects the necking area. This function provides an advantage over conventional single-position measurement, wherein a rupture outside the gauge length area causes test invalidity.
POINT PROBE
LINE PROBE
EXTREME LINE PROBE
T – TRANSVERSAL STRAIN
Allows for measuring of transversal strain in real-time. In addition to the elementary measurement probes such as Point probe and Line probe, the Alpha Transversal Strain measurement module includes the Trans Line probe with the edge detection feature. The Trans Line offers single or multiple line width measurement. This is an advantage over the conventional single-position measurement. All lines can be averaged for a precise Poisson’s ratio reading. The transversal module does not support axial strain measurement.
POINT PROBES
BEND PROBE
TRANS LINE PROBE
AT – AXIAL & TRANSVERSAL STRAIN
A bundle of Axial and Transversal modules.
TR – TORSIONAL
Allows for measurement of angular twist on cylindrical specimens in two positions. Usable in static and dynamic applications.
This module is an extension and works only with the A or T modules.
TORSION LINE PROBE
PP – POST PROCESS
This module unlocks a remarkably efficient tool for processing of previously recorded tests with sub-sequent playback and data export. Each real-time measurement method can have multiple offline records with a custom probe layout. Post-Process is an optimal solution for measurement of unique or expensive specimens and components.

DIC AREA
This module provides a strain or displacement distribution map, thereby enabling to obtain maximum available data from each experiment. This feature surpasses other technologies on the market. It helps users all over the world not just to improve the understanding of their experiments, but thanks to an easily interpretable output, also to sell their results effortlessly.
DIC Area includes the full Post-Process module.
DIC AREA
3D – Stereoscopic DIC
Alpha 3D DIC combining DIC with stereo vision, can measure the 3D displacement field and surface strain field of 3D objects.
3D DIC AREA
DIN – Device Input
Enables real-time import of external values concerning force, motion, or temperature as an analog or digital signal into Alpha. Useful mainly for post-processing or measurements taking place outdoors.
DEVICE INPUT
CL – Crack Length
This module is designed for crack length measurement of compact tension (CT) or double cantilever beam (DCB) specimens. Line probe function is included in the CL module. Line probe enables crack opening measurement providing results comparable to conventional devices.
CRACK LENGTH PROBE
LSD – LINE STRAIN DISTRIBUTION
While a full-field strain distribution via DIC Area analysis needs post-processing due to a high number of computational points, the Line Strain Distribution provides a colourful strain visualization feature during real-time measurement.
As seen below, this functionality applies to various measurement probes included in other modules.
