Non-Contact Digital Video Extensometer
Advanced, World Leading Non-Contact Extensometer
Elongation and width are measured by video camera. JIS B7741 class 0.5 elongation, and JIS class 1 width can be measured in a non-contact manner to high precision. Tests using a thermostatic chamber also can be accommodated.
- Measurement is performed in a non-contact manner.
- High Accuracy Elongation Measurements
Absolute accuracy ±1.5 μm, relative accuracy ±0.5 %
(Compliant with ISO 9513 Class 0.5, JIS B7741 Class 0.5 at room temperature)
Absolute accuracy ±3 μm, relative accuracy ±1.0 %
(Compliant with ISO 9513 Class 1, JIS B7741 Class 1 in chamber)
- Width Measurement Functionality Provided
Absolute accuracy ±2 μm, relative accuracy ±0.5 %
(Compliant with ISO 9513 Class 1, JIS B7741 Class 1 at room temperature)
Lankford value (r value), and Poisson’s ratio for films, foils and other thin specimens can be calculated
- Still image Report Functionality
Video saving during testing, S-S curve linked replay, and displays synchronized with point picking
- Assist Line Functionality for Smooth Everyday Operations
Onscreen assistance is provided for specimen mounting, movement of the grip to the test starting position, and mounting of the elongation measurement marker, all of which are required for testing.
|(Note 1)||The field of view and elongation measurement range differ. The field of view indicates the image-taking range of the cameras. In general, a field of view of (initial GL + elongation) × 1.5 to 2 is required. In addition, the field of view differs with the camera's vertical position, and the testing machine's vertical and longitudinal dimensions. The field of view may become narrow particularly when using double camera models (TRViewXD Series).|
|(Note 2)||The accuracy is defined as the absolute error with respect to the indicated value, or the relative error with respect to the indicated value, whichever is larger.|
|(Note 3)||When the gauge length is within Camera 1's field of view (120 mm), the measurement accuracy shall correspond to the accuracy of Camera 1. The accuracy in the range from Camera 1's maximum field of view (120 mm) to Camera 2's maximum field of view shall correspond to the accuracy of Camera 2.|
|(Note 4)||When the specimen's initial width is 90 mm or less, Camera 1 is used for measurement. When the value is larger than 90 mm, Camera 2 is used. The accuracy shall be in the range guaranteed for the respective camera.|
|(Note 5)||A special thermostatic chamber compatible with video extensometers is required for measuring elongation and width using the thermostatic chamber. In addition, the chamber observation window may cloud over depending on the measurement and usage conditions. Measurements cannot be performed if the gauge markers cannot be observed by the CCD cameras.|
|(Note 6)||Testing speed may be limited depending on the field of view.|
|(Note 7)||The data sampling frequency may be less than values indicated in the specifications, due to the PC performance and load.|
* Special jig may be required if the shape of a test specimen is round bar and its diameter is more than
4 mm, or when the compression and bending test.
Complete Synchronization with TRAPEZIUMX Simplifies Operability
The complete synchronization is achieved with the popular, easy-to-operate TRAPEZIUMX software for testing machines.
- Simply select the TRViewX testing conditions to automatically set the measurement mode.
- All operations from start to finish of the test can be controlled by the software.
- It is possible to measure the actual gauge length when testing starts.
* Appearance and specifications are subject to change without notice.
