STRESSTECH
is the premier research rheometer specifically designed for the serious
rheologist. Developed for research and development, the instrument
couples ultra low position resolution and a wide torque range, with our
patended Differential Pressure Quantitative Normal Force Sensor, and
Windows XP compatible RheoExploer V5 operational software. Steady shear,
transient (creep/stress relaxation) and periodic (dynamic oscillation)
testing modes are available. Samples can range from low viscosity fluids
to high modulus solid materials. The instrument is built around a
dedicated, on board high speed computer, for unprecedented performance,
versatility, and reliability. Remote control operation, remote
diagnostics, and service is available via the internet.The patented Differential Pressure Quantitative Normal Force Sensor is non-interactive, and does not cross-talk with the torque signal. The Normal Force Sensor has a wide dynamic range and can be used for both user selectable constant force loading and quantitative normal force measurements. Neither the normal force or torque signals interferes with the motion, or applies any external forces on the air bearing. This technology is unequaled in the industry. The instrument has automatic, real time, inertia compensation (not a software correction after the data is collected), and automatic temperature compensation of the gap during temperature sweep experiments. RheoExplorer is a true 32 bit Windows interface designed for Windows XP and Windows Vista with true multi-tasking capability. The user can easily transfer data to any other Windows application, can support any Windows compatible output device, and can send data directly to a network server. Both Time/Temperature Superposition, IRIS (licensed from Dr. H. Winter at University of MA), and advancned rheological modeling are available. Being built around a dedicated, on board computer, the instrument hardware provides adaptive, direct control for constant rate and constant strain measurements. All electronics are built into the instrument to minimize bench space requirements. Output from the instrument is through an industry standard RS232 line to any PC with an open com port. There is no interface card or software key limitations, and the computer is not dedicated to just running the rheometer.
