Optical extensometer
The optical extensometer DeltaL is a non-contact deformation measuring device for material testing based on high-resolution video technology using measuring marks applied to the specimen.
The optical extensometer is used for optical non-contact strain measurement in tensile, compression and bending tests
Advantages and Features
- Non-contact optical measuring device, also suitable for thin and sensitive specimens
- Easy to set up
- Laser alignment support
- Suitable for both strain measurement and strain control
- Strain value is transmitted via stable analog signal
- 0.5 μm resolution, class 0.5 according to ISO 9513 and ASTM E83 B-1 possible
- Enables the determination of elastic parameters:
- elastic straight line
- equivalent yield point
- yield strength
- elongation at break in the specified field of view
- Can be used for strain measurement in temperature chambers/ furnaces
- Various models available for longitudinal or longitudinal and transverse strain measurement (DeltaLW 80)
- Simple operation directly via LabMaster testing software
- Stereoscopic camera arrangement with 2 cameras
- reduces potential interferences
- enables precise measurement of length changes, even with an inclination angle of the test plane of up to 6°
- Various options for convenient specimen marking using a stamp or template
