Our laser extensometers have a variety of advantages over alternative methods and products:
 |
Optical Direct Strain Measurement |
Non intrusive operation from elasticity till break; high resolution of 2 ppm or 6 ppm |
 |
Strain distribution in fine detail |
With locally resolved strain measurement heterogeneous material behavior can be described easily |
 |
No drift in long time investigation |
Continuous monitoring of operational extensometer parameters allows drift free measurements over long periods, e.g. with creep tests at ceramics |
 |
Poissons´s ratio in one single experiment |
Measuring longitudinal and lateral strain simultaneously at the same experiment with the high accuracy of our laser extensometers is the prerequisite for determining Poissons´s ratio |
 |
Set value for control of the test apparatus |
Strain controlled experiments on base of standard strain signal, maximum local strain, minimum local strain are easily possible |
 |
Reference length is self memorized |
The laser extensometer determines all reference lengths at the beginning of the experiment |
 |
Determination of damaged Specimen areas for lacal failure analysis |
The locally resolved strain measurement directly "points" to the area of failure |
 |
Applicable at climatic chambers and furnaces |
Adaptations make the laser extensometers also suitable at climatic chambers, resistance furnaces, inductive furnaces or pressure chambers |
 |
Up to six scanning beams for more detailed strain distributions |
Extensions of the base models of laser extensometers allow wide variety of strain analysis |
 |
Compatibility with major brands of tensile testors |
Integrations in tensile testing equipment of well known manufacturers are readily available |
