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
5. Maximum deformation: 6091U series 25 mm, 6091J Series 4mm
6. Output terminal connector: four core or five core plugs, etc
The above is general parameters, if users have special requirements, we can provide special
production according to need. Please inform us when ordering.
