Automatic determination of viscosity by rotary viscosimeter VRTS

Abstract

If it is necessary to determine the viscosity at a given temperature, various viscosimeters of various types, mostly rotational viscometers can be used. One of them was developed at the Department of Measuring Technique of Samara State Technical University. It contains two channels: a viscosity measuring channel and a temperature measuring channel. Rotation of the measuring rotor is carried out by a drive through a calibrated spring, the angle of twisting of which is proportional to the torque, which is converted into a pulse-width signal. The microcontroller measures and analyzes this signal and a signal proportional to temperature, converts them into a digital code and outputs the information on viscosity and temperature through the output port in a digital form.
