The MFL can be connected to partly or fully automatic testing machines with hydraulic grips. The strain can be measured from the elastic range to fracture for almost all types of samples. The strain can be measured from the elastic range to fracture for nearly all types of 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)
