Optical Extensometer

The optical extensometer is suitable for reliable, accurate strain measurement in tensile and hysteresis tests on highly ductile, highly elastic and contact-sensitive materials. It provides accurate, contact-free measurement even under extended temperature conditions in environmental chambers.

• High resolution and measuring accuracy.
• Interference from extraneous light and reflecting edges is eliminated via pattern recognition, enabling reliable operation using continuous lighting, with further enhanced sensitivity.
• Integrated microprocessor control simplifies operation, whether the extensometer is being used for manual tensile testing or is integrated into an robotic testing process. The test sequence runs constantly, without time-consuming positioning operations and with operating steps reduced to a minimum.
