Extensometers are devices that are used to measure strain or deformation in materials under stress. There are various types of extensometers available on the market, and new systems are continually being developed with more advanced features. Here are a few of the latest extensometer monitoring systems:
- Digital Image Correlation (DIC) Extensometers: DIC systems use digital cameras to capture images of a material or structure as it undergoes deformation. These images are then analyzed to determine strain values. This technology allows for highly accurate and non-contact measurement of strain.
- Wireless Extensometers: These systems use wireless technology to transmit data from the extensometer to a receiver, eliminating the need for data cables. This makes installation and data collection more convenient and allows for real-time monitoring of strain.
- Fiber Optic Extensometers: Fiber optic sensors are integrated into the material being tested, and strain is measured by analyzing changes in the light transmission through the fiber. This technology allows for highly accurate and continuous monitoring of strain, even in harsh environments.
- Video Extensometers: These systems use video cameras to capture images of the material being tested, and software analyzes the images to determine strain values. This technology allows for non-contact measurement of strain and can be used in a wide range of applications.
- Capacitive Extensometers: Capacitive sensors measure changes in electrical capacitance as a material undergoes deformation. These systems are highly accurate and can be used to measure strain in a wide range of materials.
Overall, the latest extensometer monitoring systems incorporate advanced technology to provide highly accurate and non-contact measurement of strain in a wide range of materials and environments.
