摘要: A universal measuring apparatus for the determination of rheological properties viscous, viscoelastic and purely elastic materials measures said solely by axial movement mechanical components (''axial rheometer''). The comprises a stiff metal frame (1, 2, 3) which one horizontal part (3) is used as mount force transducer (9) with little or practically no deflection at full scale load on an exchangeable piston-shaped holder (10) mounted axially while opposing (1) forms displacement (4) micropositioner type acts directly upon moveable (6, 8), being able to cause continuously determine position 8) accuracy approximately 0.1 νm, thereby producing deformation in sample (11) positioned between holders (8, 10).
