VISCOSITY DETECTOR Russian patent published in 2005 - IPC

FIELD: inspection of technological fluids.

SUBSTANCE: detector has tuning fork. Axial rod of tuning fork passes through base of the tuning fork. Piezoelectric converters and counterweights are mounted at each foot of tuning fork at parting line. Tuning fork is disposed vertically and is suspended at string stretchers by axial rod. Counterweights are shifted relatively parting lines at opposite directions in such a way that at reciprocal oscillations of feet of tuning fork the periodic torque generates relatively vertical axis and sample body disposed at the end of axial rod makes torsional vibrations.

EFFECT: improved precision of measurement.
