Abstract
Viscometer with a spindle (4) mounted on a shaft (8) supported via axially spaced, e.g. three inches, bearings (12,14) and driving a transducer rotary member via a stiff rotationally resilient member, the latter providing substantially all the resistive torque to viscous drag imparted to the spindle by an outer driven rotating member (6) when the spindle and rotating member are immersed in a liquid whose viscosity is to be measured, the viscometer being constructed with a handle (38) that encloses motor drive and electronic components of the viscometer, these features, as a whole, providing explosion protection and portability of the viscometer with sensitivity appropriate to portable usage.
