| The Synchro-Lectric Viscometer rotates a cylinder or
disc 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
position of the red pointer on the Viscometer's dial, is pro- portional to the
viscosity of the fluid for any given speed and spindle. |
