Laserextensometer

Scanning Laser Extensometers for measuring deformation at static, quasistatic and cyclic loading.

high resolution and accuracy, insensitive to small variations of the working distance

measurement of large strain, scanning range up to 500 mm

simultaneous measurement of longitudinal and lateral strain, determination of Poisson's ratio

strain measurement at biaxial tensile test

optimised for shear tests, measuring crack opening and three-point-bending-tests

Models Sensor, 2 Point and Multi Point System of the several laserextensometer types

Working principle of the laserextensometer

measuring and evaluation software with calculation of the characteristic values

integration in climatic chambers and furnaces

calibration of the extensometer
