More Information
Summary:Viscometer (150) with a rotor (108) connecting a magnet holder (62) which penetrates a sealed movable piston (96) and rotatable by a coupling magnet (58) and a driving magnet (64) to shear a tested fluid thus imparting torque to a bob (42) mounted on a bob shaft (30) supported via a pair of bob shaft bearings. A spiral spring (140) restricts the rotation of bob shaft (30). Magnetometer (10) measures the angular position of a top magnet (142) connected to the top of bob shaft (30). This angular position information is further converted to the viscosity of the tested fluid.
