Abstract
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.
