ABSTRACT:
A viscosimeter for measuring the viscosity of liquids and, in particular, viscous material such as polyester resins and the like which includes a rotatably driven cup in which the liquid sample to be measured is introduced and heated and a torsion wire and spindle assembly suspended from an upstanding support with a plunger mounted on the lower end of the assembly by means of a thermal isolation coupler for immersion in the sample, the support being provided with an adjustment mechanism including a clamp for positioning the plunger in a calibrated position within the sample together with a capacitive-type transducer connected to an electronic readout circuit whereby rotation of the cup rotates the torsion wire and spindle assembly due to the drag of the liquid until the restoring force of the torsion wire just balances the drag of the liquid to provide a readout from the readout circuit corresponding to the viscosity of the liquid.
