    Abstract: Apparatus and method for producing a linear voltage versus thickness output for a radio frequency glass thickness gauge. One type of thickness measuring device for glass containers uses the attenuation of a radio frequency signal as a measure of thickness. The thickness signal is a voltage which varies nonlinearly as a function of thickness. This invention is a circuit for linearizing the nonlinear thickness signal. The input resistance to an operational amplifier is varied as a function of the thickness signal voltage. This creates a variable gain for the operational amplifier and consequently results in the generation of a linear thickness versus voltage relationship. Zener diodes are used as nonlinear variable resistors in two different thickness ranges to give a nonlinear, variable, input resistance to the operational amplifier.

    Abstract: A method for measuring average thickness of a metal or alloy coating on a metal or alloy substrate using an X-ray fluorescence (XRF) spectrometer is used when the coating has an uneven surface at different distances from a measurement window of the XRF spectrometer. The method includes measuring elemental composition of the coating or substrate using the XRF spectrometer and obtaining the average thickness of the coating using a calibration relationship between coating thickness and elemental composition of the coating or substrate. The metal or alloy coating may be a metal or alloy coating of a plurality of outer armor wires wrapped around a cable. The method may be used to analyze coating thickness changes over time or along the length of the cable, or to analyze a corrosive environment in order to choose optimal material for a metal or alloy coating.

    Abstract: A system includes a top scanner head configured over a coated substrate. An x-ray sensor and a second x-ray sensor scan the coated substrate. At least one of the x-ray sensor and second x-ray sensor is tuned to an energy level below an absorption peak and at least one of the x-ray sensor and second x-ray sensor is tuned to an energy level above the absorption peak. The x-ray sensor and second x-ray sensor scan a same sheet spot on the coated substrate. A bottom scanner head is configured underneath the coated substrate to provide a location for a detection of x-rays for the x-ray sensor and the second x-ray sensor.
