Viscometer

Abstract

The invention provides a viscometer. The viscometer comprises a servo motor and a viscosity sensor, wherein the servo motor comprises a servo motor body, a motor shaft, a motor rotor, a permanent magnet and a coder, wherein a first end of the motor shaft is arranged inside the servo motor body; the motor rotor, the permanent magnet, the coder are fixedly connected with the first end of the motor shaft; a second end of the motor shaft extends outside the servo motor body, and is directly and fixedly connected with the viscosity sensor; the rotation of viscosity sensor is lagged under the actionof viscosity torque generated in liquid to be tested; the coder is used for reading a lagging angle fed back by the motor shaft, and liquid dynamic viscosity of the liquid to be tested is calculatedaccording to the lagging angle. The viscometer is simple in structure, the rotation of the motor shaft and the viscosity sensor device is insusceptible to the interference of external environment, sothat the adaptivity of the viscometer in a plurality of industrial flows is improved, and the accuracy of the liquid hydraulic viscosity measured by the viscometer is increased.
