Heavy-Duty Fully Automatic Extensometer Series MFL
There low clamping force combined with high measurement accuracy makes them suitable for a wide range of specimens and materials, even for small, notch sensitive test samples.
When used in combination with the transverse models, the MFL extensometers are ideal for testing the deep-drawing properties of thin sheets.
Key Features
-
Two-sided measurement by means of four measuring ensors
-
Very low clamping forces even allow testing of thin wires and foils
-
Very high resolution of up to 0.1 μm over the complete measuring range
-
The gauge length position and value can be precisely set under computer control
-
The round knife edges can be utilized along their whole perimeter by rotating them
-
Accuracy class 0.5 (EN ISO 9513)
-
The gauge length (Le) is adjusted automatically set through the Application Software and the measuring levers are automatically open and closed
-
Measuring until sample failure or to a reference load, stress, strain or drop of a load or stress
-
Automatic returning to initial position and adjustment of Le ready for the next test
-
The measuring springs of a right and left arm pair are connected in parallel to obtain an average value which is important if the sample deforms none homogeneously
-
Initial gauge length from 10 mm
-
Automatic movement to the position and gauge length
-
Automatic attachment to specimen
-
Very low clamping forces (ca. 0.5 N)
-
Measuring displacement of 300 (MFL-300), 500 (MFL-500) or 800 mm (MFL-800) mm minus gauge length
-
Lowest activating forces (<1 cN)
