Abstract

Bei einem Verfahren zur Bestimmung der Viskosität eines Fluides (2), wobei das Fluid in einen Hohlzylinder (1) gefüllt wird, wobei der mit dem Fluid (2) befüllte Hohlzylinder (1) um eine Rotationsachse (3) mit der Drehzahl (n2) rotiert wird, wodurch ein Schwimmkörper (4), welcher Schwimmkörper (4) im Hohlzylinder (1) angeordnet und relativ zum Hohlzylinder (1) um die Rotationsachse (3) rotierbar ist, mittels des Fluids um die Rotationsachse (3) mit der Drehzahl (n1) rotiert wird, wodurch ein vom Schwimmkörper (4) umfasstes Magnetsystem (5), welches Magnetsystem (5) lagefest mit dem Schwimmkörper (4) verbunden ist, um die Rotationsachse (3) rotiert wird, wird, damit das Verfahren über sehr weite Viskositätsbereiche des Fluides eine hohe Messgenauigkeit aufweist, vorgeschlagen, dass durch die Rotation des vom Schwimmkörper (4) umfassten Magnetsystems (5) in einer Spule (6) eine elektrische Spannung induziert wird, dass eine die elektrische Spannung U1 charakterisierende physikalische Größe ermittelt und mittels der physikalischen Größe die Viskosität des Fluides (2) bestimmt wird.In a method for determining the viscosity of a fluid (2), the fluid being filled into a hollow cylinder (1), the hollow cylinder (1) filled with the fluid (2) being rotated about an axis of rotation (3) at the rotational speed (n2) whereby a floating body (4), which floating body (4) is arranged in the hollow cylinder (1) and rotatable relative to the hollow cylinder (1) about the rotation axis (3), is rotated by means of the fluid about the rotation axis (3) at the speed ( n1) is rotated, whereby a floating body (4) comprises magnet system (5), which magnetic system (5) fixedly connected to the floating body (4) is rotated about the axis of rotation (3) is, so that the process over a very wide Viscosity ranges of the fluid has a high accuracy, proposed that by the rotation of the floating body (4) encompassed magnetic system (5) in a coil (6) an electrical voltage is induced that a the electrical voltage U1 characterizing physika determined by the physical size and the viscosity of the fluid (2) is determined.
