This system consists of a mechanical unit, a control unit (console), a data processing unit and a printer. The dynamic or steady state flow data are automatically printed out. An outer cylinder (sample container) is connected to a torsion wire assembly supported by a pair of magnetic bearings. The angular displacement is detected by a pair of variable differential transformers. In clinical application of this rheometer, authours have confirmed that the viscosity and viscoelasticity of blood from diabetic patients are higher than for normal subjects.","PeriodicalId":79205,"journal":{"name":"Biorheology.
