Abstract:
PCT No. PCT/GB89/01173 Sec. 371 Date Jun. 3, 1991 Sec. 102(e) Date Jun. 3, 1991 PCT Filed Oct. 3, 1989 PCT Pub. No. WO91/05235 PCT Pub. Date Apr. 18, 1991.Apparatus for measuring the fluid characteristics of a sample comprises a frame, at least a first stage mounted on the frame for rectilinear movement, first mounting means mounted on the first stage, and a first member carried by the mounting means, a second member mounted to the frame in register with the first member, at least one of the first member and second member being readily interchangeable, positioning means for moving the first stage to adjust the relative positions of the members whereby a sample carried by one of the members can be brought into contact with the other of the members and whereby to adjust the spacing between the first and second members to a preselected distance, a device for vibrating the first mounting means rectilinearly, and thus the first member carried thereby, at a preselected frequency. A Piezo-electric device is provided for vibrating the first member rectilinearly as indicated by the arrow and a force transducer detects the phase angle and amplitude of the vibration transmitted through the sample. Relationship between the vibration applied by the device and those received by the transducer are used by a controlling computer to calculate the characteristics of the sample. The apparatus can operate over a wide range of frequencies; the sample temperature can be accurately controlled.
