Extensometers

TW-6091  Series Features
1.1 TTM-6091U series axial deformation extensometer, which is applicable to metal, non-metallic 
       material test. It includes regular extensometer, average strain extensometer, special 
       extensometer (large standard steel hinge line, concrete, rocks, wood, etc.). Used to
       measure elastic modulus E, provisions non-proportional extension intensity RP, stipulated
       total extension strength RT, various elongations, strain hardening exponent N and other
       parameters.
1.2 TTM-6091J series fracture mechanics and the lateral deformation of extension plan, is used to
       measure Poisson's ratio U, plastic strain R, KIC, COD parameters.
       Also used in reverse shear modulus G, regulation disproportional torsion stress RP (for  
       example Rp0.015, Rp0.3, etc.) of the torsion extensometer.

Technical parameters
1. The strain gauge resistance: 350 ohms
2. Bridge voltage value: acuities 6V (DC, AC all can)
3. Output sensitivity: about 2mV/V
4. Extensometer gauge length: 6091U series 20~200 mm, 6091J series 5~25 mm
