摘要 |
A viscometer has a hollow torsion bar to be dipped into a liquid, the viscosity of which is to be measured, a probe constituted by a massive hollow body mounted on the distal end of the hollow torsion bar, a vibrator mounted in the hollow body for producing vibrations in a circular direction around the axis of the torsion bar, a vibration detecting sensor mounted in the hollow body for detecting vibrations of the vibrator, a wiring pipe within the hollow torsion bar and spaced from the interior surface thereof and having conducting wires therein extending to the vibrator and to the sensor and adapted to be connected to an external vibrator driving circuit and an external vibration sensing circuit.
