Dynamic Modulus Tester
LH-551, LH-552
The Dynamic Modulus Tester is a complete system that measures Sonic Velocity through materials. Physical properties derived from sonic velocity include modulus
of elasticity, material anisotropy, molecular orientation
in fibers and films as well as orientation of fibers in a web.
APPLICATIONS
Yarns such as Carbon, Glass, Polyester, Nylon, Tapes, Monofilament, or strips of most materials including Nonwovens
ADVANTAGES
• Small, table-top instrument for very quick and
accurate measurement of sonic velocity through
materials such as yarns, fibrous webs, films, tapes,
paper and others
• Excellent tool for Production Control and R&D
• Non-destructive testing for most materials
• Same machine can be used to test both yarns and
material strips by changing the sample mount
FEATURES
• Digital display of the transit time through material
• User friendly software program that calculates the
sonic velocity automatically
• Fiber Scanner option for yarn and Planar Mount
option for sheet material testing
OPERATION
The Dynamic Modulus Tester is a complete system that measures the velocity of the sonic pulses in materials such as yarns, films, tapes, non-wovens, and papers. The test materials is contacted by two transducers. The DMT software calculates the sonic velocity, which is used to measure the physical and chemical structure of materials.
OTHER USES
• Evaluation of experimental materials
• Production quality control
• Research, Assist in product development
