Resonant Sensors For Fluid Properties Measurement

摘要

A resonator that includes an elastic tube defining an interior surface and a conductor threaded through the elastic tube. Solid material fills space between the conductor and the elastic tube interior surface, such that motion of the conductor is directly transferred to the elastic tube. In a preferred embodiment, the elastic tube 14 is electrically conductive and said solid material insulates said conductor from said elastic tube.

1. A resonant sensor for measuring properties of a fluid, comprising:
(a) an elastic tube defining an interior surface; (b) a conductor threaded through said elastic tube; (c) solid material joining said conductor to said elastic tube interior surface, so that force exerted on said conductor is directly transferred to said elastic tube; and (d) a magnet assembly that creates a magnetic field, thereby providing a Lorentz force on said conductor when a current is passed through said conductor.
