Abstract

Official abstract text for this publication.

Measurement of pressure of a fluid in a vessel using a cantilever spring in the vessel; a magnet connected to the cantilever spring in the vessel; an electromagnet outside of the vessel operatively connected to the magnet and the cantilever spring in the vessel, wherein the electromagnet induces movement of the magnet and the cantilever spring in the vessel, and wherein the movement is related to the pressure of the fluid in the vessel; a receiving coil operatively positioned relative to the magnet, wherein movement of the cantilever spring and the magnet in the vessel creates an electromotive response in the coil; and a controller analyzer connected to the receiving coil, wherein the controller analyzer uses the electromotive response in the coil for measuring the pressure of the fluid in the vessel.

First claim

Opening claim text (preview).

The invention claimed is: 1. An apparatus for measuring unknown internal pressure of a fluid inside of a vessel wherein the vessel has a vessel wall, comprising: a sensor located inside of the vessel for sensing the unknown internal pressure of the fluid inside the vessel wherein said sensor is a resistive sensor; a receiving unit located outside of the vessel; a controller analyzer operatively connected to said receiving unit, and a magnetic induction communication system having a first induction coil located inside of the vessel wall and a second induction coil located outside of the vessel wall, wherein said magnetic induction communication system is operatively connected to said sensor and said receiving unit and wherein said magnetic induction communication system communicates said sensed unknown internal pressure of the fluid inside the vessel from said sensor to said first induction and from said first induction coil to said second induction coil and from said second induction coil to said receiving unit and from said receiving unit to said controller analyzer for measuring the pressure of the fluid in the vessel. 2. An apparatus for measuring unknown internal pressure of a fluid inside of a vessel of wherein the vessel has a vessel wall, comprising: a sensor located inside of the vessel for sensing the unknown internal pressure of the fluid inside the vessel wherein said sensor is a capacitive sensor and wherein said sensor includes a diaphragm that responds to the unknown internal pressure of the fluid inside of the vessel; a receiving unit located outside of the vessel; a controller analyzer operatively connected to said receiving unit, and a magnetic induction communication system having a first induction coil located inside of the vessel wall and a second induction coil located outside of the vessel wall, wherein said magnetic induction communication system is operatively connected to said sensor and said receiving unit and wherein said magnetic induction communication system communicates said sensed unknown internal pressure of the fluid inside the vessel from said sensor to said first induction and from said first induction coil to said second induction coil and from said second induction coil to said receiving unit and from said receiving unit to said controller analyzer for measuring the pressure of the fluid in the vessel.
