But only with some expensive torque sensor (~1000$) possible. But we are looking a 1996-02-01 · Low-cost rotational viscometer with digital readout that was well-suited for measuring viscocity was constructed with two dc motors, a rotor, a measuring cup, and milivolt recorder. This rotational viscometer can be used for quick, unsophisticated tests and comparative measurement. The viscometer requires no further calibration once it is set. Calibration with Newtonian substances indicates rotational viscometer, which has been solved by Krieger and co-workers for various sets of boundary conditions [Krieger and Maron, 1952]: D 1 2 Z R c R b f.˝/ ˝ d˝.2:10/ where is the angular velocity of the spindle with respect to the cup, ˝is the shear stress in the fluid at any point in the system, f.˝/DP is the rate Operation Procedure for Viscometer: Ensure that equipment is clean. Check the level of instrument with the help of spirit level on the top of the Viscometer, and if required set level with help of three screw on triangle bottom.

User can calibrate viscometer All Spindles made of 316 stainless steel The Rotating disk viscometer, or "Mooney Machine" as it is sometimes referred to in the rubber industry, is the standard viscometer for measuring material viscosity and scorch time for rubber before vulcanization.It was developed in the 1930s by Melvin Mooney. For a specific temperature, scorch time describes how long it will take the material to vulcanize. Rotational viscometer is a device that collects data on materials viscosity performance under various temperature conditions. The rotational viscometer fundamentally is of two parts- one is the head component with a motor and the other is spindle that is motor-powered. Perform viscosity measurements with ease! The self-explaining Thermo Scientific™ HAAKE™ Viscotester™ 3 rotational viscometer ensures quick, reliable tests for QC applications.

A total of 28 samples were investigated with  av I Erlandsson · Citerat av 2 — The measurements of viscosity are performed with a dynamic rotational viscometer. This equipment is not an ordinary method for viscosity measurement of  Cox-Merz rule; Tikhonov; tube viscometer; rotational viscometer; homogenisation; shearing;.

Rotational viscometers are the industry standard in determining absolute viscosity of all types of liquids with viscosities as high as 320 million centipoise. Digital models are available for low - medium - high viscosity materials. User can calibrate viscometer All Spindles made of 316 stainless steel The principle of operation of this Viscometer is the same as all other rotational viscometers: a spindle (cylinder or disk) is submerged in the sample to be tested, measuring the force applied to overcome the resistance against rotation or flow. A spring is connected between This precision Digital Rotational Viscometer is designed and engineered offering the newest microchip technology to ensure high accuracy and high precision combined with a user-friendly and large LCD display with backlight, easy programming features and an ergonomic design, continuous speed control and a set of different available spindles.

Rotational viscometers are relatively easy to use but their measurement inaccuracy is at least ±10%. All types have some form of element rotating inside the liquid at a constant rate. One common version has two coaxial cylinders with the fluid to be measured contained between them. Rotational viscometers have become a standard in virtually all industries. They measure viscosity by sensing the torque required to rotate a spindle at constant speed while immersed in fluid.
