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)
