VIBRATION VISCOSIMETER SENSOR Russian patent published in 2016 - IPC G01N11/10 

FIELD: measurement equipment.

SUBSTANCE: invention relates to the field of detection of shear viscosity by a vibration method in small volumes of liquid in the local area with the simultaneous measurement of its temperature. The vibration viscosimeter sensor comprises a miniature inductance sensor of the current position of a miniature probe, a thermocouple meter of the probe temperature, a mechanical oscillating system, comprising a probe, a base with two stands, two elastic heterogeneous conductors, an electromechanical vibrator. At the same time heterogeneous conductors are rigidly fixed to stands and the surface of the probe to form simultaneously a measuring junction of a thermocouple temperature meter, reference junctions are connected at the outer side with metal stands, the electromechanical vibrator in the form of a telephone capsule is removed outside the vibration sensor and is installed to provide for acoustic interaction with the stiff base. At the same time the parts of the sensor submerged into liquid, at least, elastic conductors and a spherical probe, have a protective film coating.

EFFECT: provision of the high sensitivity of a vibration viscosimeter sensor to small changes in liquid viscosity by the development of the vibration viscosimeter sensor with an expedite oscillating system.
