An electrical capacitance volume tomography sensor for use in high temperature, high pressure applications for measuring or imaging a flow within the sensor, the sensor comprising an outer pressure vessel, a plurality of electrodes placed within the outer pressure vessel, a plurality of threaded studs, wherein one of the threaded studs is attached to one of the plurality of electrodes, a coating or layer is placed on the plurality of electrodes for electrically isolating the plurality of electrodes, a plurality of holes in the outer pressure vessel for allowing terminal connections to the plurality of electrodes within the outer pressure vessel, wherein each of the plurality of holes accepts one of the plurality of threaded studs, and a plurality of gaskets, where one gasket is placed at each of the plurality of holes to seal the pressure at each of the holes in the outer pressure vessel by placing one gasket concentric around one threaded stud and conforming each gasket between a back of an electrode and the inside wall of the pressure vessel by tightening each of the plurality of nuts on each of the threaded studs.

Extreme-condition sensors for use with electrical capacitance volume tomography and capacitance sensing applications

A system and method for Displacement Current Phase Tomography. The present system invention obtains a linear relationship between mutual displacement current from a sensor (output current of the measuring electrode terminals) and the area (or volume) of an object to be imaged in the imaging domain. The system uses capacitance sensors and utilizes the phase of the measured current, in addition to the amplitude, to reconstruct an image.

Displacement current phase tomography for imaging of lossy medium

The present invention uses a plurality of magnetic field sources and magnetic field sensors mounted against a surface. Based on the mass of ferromagnetic material, such as steel, the magnetic field sensors detect variable magnetic field strength and this variance is proportional to the mass of ferromagnetic material being detected. An electronic device reads the magnetic field values and uses the information to quantify the ferromagnetic material in the surface or inside the volume of the construction component.

Differential magnetic field tomography

A control system and data acquisition system for an electrical capacitance tomography sensor comprised of a sensor having a plurality of electrodes, where each electrode is further comprised of a plurality of capacitance segments. Each of the capacitance segments of each electrode can be individually addressed to focus the electric field intensity or sensitivity to desired regions of the electrodes and the sensor.
