Brookfield Dial Viscometer 50-60 Hz
The Brookfield Dial Viscometer measures fluid viscosity at given shear rates. Viscosity is a measure of a fluid's
resistance to flow. The Dial Viscometer rotates a sensing element in a fluid and measures the torque
necessary to overcome the viscous resistance to the induced movement. This is accomplished by driving the
immersed element, which is called a spindle, through a beryllium copper spring. The degree to which the spring
is wound, indicated by the red pointer, is proportional to the viscosity of the fluid.
The Viscometer is able to measure over a number of ranges since, for a given spring deflection, the actual
viscosity is proportional to the spindle speed and is related to the spindle's size and shape.
For a material of given viscosity, the resistance will be greater as the spindle size and/or rotational
speed increase. The minimum viscosity range is obtained by using the largest spindle at at the highest speed;
the maximum range by using the smallest spindle at the slowest speed.
