Rheometer high frequency acoustic device measuring the viscosity of a fluid using this rheometer.

摘要

The invention relates to acoustic rheometer OPERATING IN THE FIELD OF HIGH FREQUENCY. The invention resides in THE FACT THAT rheometer comprises a transducer (3) TORQUE IS A GLASS CLASS OF SILENITAS, HEIGHT determining the resonance frequencies of the torsional mode and has excitation means ELECTRIC. Additional DETECTOR (2) is an alloy rod of iron and nickel has a coefficient thermoelastic very small, which is connected rigidly to the transducer (3), ELECTED Diameters RESPECTIVE (DT) Y (DC) TRANSDUCER AND DETECTOR FOR REFLECTION COEFFICIENT TRANSDUCTOREN Interface printing systems ink.
