Title: Apparatus for measuring viscous drag and coefficient of viscosity of object
Inventor: MICHIMATA TOORU
IPC: G01N11/12
Filed: 1995-02-27
Abstract: PURPOSE: To shorten the time required for measuring the coefficient of viscosity while enhancing the reliability of data by piercing an object in a container with a needle, reciprocating the needle at a constant speed in the longitudinal direction and then measuring the load being applied to the container. CONSTITUTION: A sample (object) 2 in a container 1 placed on an electronic balance 4 is pierced up to a predetermined depth with a detection needle 3 while being heated in an electric furnace 5. When the needle 3 is reciprocated at a constant speed V in the longitudinal direction through a driver 6, resisting force produced by the viscous drag of the sample 2 is transmitted to the container 1. The resisting force (load) P is measured by the balance 4 and the viscosity η is determined based on the load P, the time required for the tip of the needle 3 to arrive at a predetermined depth S, the diameter of the needle 3, etc. Since the viscosity η is proportional to the load P for a set depth S, the speed V and the depth S can be set arbitrarily within a practical range. Consequently, the period of reciprocal motion can be set within an easily measurable range and short time measurement can be realized while enhancing the reliability of data.
