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 (does not apply to Type DMS Length 1).
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 (Type DMS Length 1 only).

Description of application

The DMS Length 1 extensometer is intended for fixed gauge-lengths L0 = 25 mm and L0 = 50 mm with a measuring range of 25 mm.

Extensometer types DMS Length 2, DMS Length 3 and DMS Length 4 are intended for fixed gauge-lengths L0 = 20 mm and L0 = 10 mm with a measurement travel of 2 mm in the tensile direction and 1 mm in the compression direction.

The DMS Length 5 is a double-sided clip-on extensometer with measurement systems delivering two individual signals. It is intended for fixed gauge-length L0 = 10 mm with measurement travel of 1.5 mm in the tensile and compression directions.

DMS Length 3, DMS Length 4 and DMS Length 5 are suitable for use in temperature chambers. DMS Length 5 is also suitable for use with HCCF.

Suitable for use in temperature chambers; satisfies ISO 6892-1:20117 Annex G. Not suitable for tests up to break.

Strain gauge, width

This transverse strain extensometer is designed for use in connection with sensor arm extensometers or without extensometer. It is intended for fixed specimen widths B₀ = 20.5 mm ... B₀ = 16.5 mm. The measurement displacement is 4 mm.

For determination of Poisson’s ratio on fiber-reinforced composite materials to ISO 527-1.
Selection of different probes for adaptation to the specimen dimensions.

Strain gauge biax 2501-2

The 2501-2 biax clip-on-extensometer can be used specifically for determining the change in length and width of specimens made of fiber-reinforced composites or metal.

This clip-on extensometer is suitable for determining the in-plane shear strength (IPS) and for determining Poisson's ratio.

With a wide temperature range of -70 ... +175 °C the strain gauge-based clip-on extensometer is particularly suitable for use in temperature chambers.
