Strain gauge clip-on extensometer
Strain gauge clip-on extensometers are manual clip-on extensometers, that are clamped to the specimen. With various preset gauge-lengths they are suitable for use on metal and plastic specimens.
- Measuring systems possess excellent linearity, providing reliable test results.
- Lightweight, miniaturized construction, ideal for short specimens.
Advantages & features
- Excellent linearity for reliable test results.
- High resolutions enable measurement of very small deformations during test.
- Lightweight, miniaturized construction, ideal for specimens with small parallel length.
- Initial gauge length can optionally be reset from 10 to up to 100 mm using extension pieces.
- Temperature-resistant measurement systems for use from -50°C to +200°C.
- Extensometers for two-sided measurement of specimen deformation, enabling exact determination of Young's modulus and engineering elastic limit.
- Variable measurement options are possible on extensometers with 2 separate measurement systems; individual signals or mean-value signal can be displayed.
- While attached to the specimen the extensometer is prevented by limit stops from exceeding the measurement travel and protected in the event of specimen break.
