Abstract

A rotary viscometer is described in which the force measuring device for measuring the force acting on a measuring surface, normal to the surface thereof, is contained within a separate housing releasably connected to the remainder of the apparatus. The force measuring device comprises a beam and the force is communicated to the beam by an intermediate thrust member which is stiff and does not yield to axial loads but will move readily to other directions to accommodate misalignment.
