Thick film hydrogen sensor

Hoffheins, Barbara S; Lauf, Robert J

Title: Thick film hydrogen sensor

Abstract

A thick film hydrogen sensor element includes an essentially inert, electrically-insulating substrate having deposited thereon a thick film metallization forming at least two resistors. The metallization is a sintered composition of Pd and a sinterable binder such as glass frit. An essentially inert, electrically insulating, hydrogen impermeable passivation layer covers at least one of the resistors.

Process for manufacture of thick film hydrogen sensors

Patent Perdieu, Louisa H [Overland Park, KS]

A thick film process for producing hydrogen sensors capable of sensing down to a one percent concentration of hydrogen in carrier gasses such as argon, nitrogen, and air. The sensor is also suitable to detect hydrogen gas while immersed in transformer oil. The sensor includes a palladium resistance network thick film printed on a substrate, a portion of which network is coated with a protective hydrogen barrier. The process utilizes a sequence of printing of the requisite materials on a non-conductive substrate with firing temperatures at each step which are less than or equal to the temperature at the previousmore » step. « less

Thin film hydrogen sensor

Patent Cheng, Yang-Tse [Rochester Hills, MI]; Poli, Andrea A [Livonia, MI]; Meltser, Mark Alexander [Pittsford, NY]

A thin film hydrogen sensor, includes: a substantially flat ceramic substrate with first and second planar sides and a first substrate end opposite a second substrate end; a thin film temperature responsive resistor on the first planar side of the substrate proximate to the first substrate end; a thin film hydrogen responsive metal resistor on the first planar side of the substrate proximate to the fist substrate end and proximate to the temperature responsive resistor; and a heater on the second planar side of the substrate proximate to the first end.

Thin-film fiber optic hydrogen and temperature sensor system

Patent Nave, Stanley E [Evans, GA]

The invention discloses a sensor probe device for monitoring of hydrogen gas concentrations and temperatures by the same sensor probe. The sensor probe is constructed using thin-film deposition methods for the placement of a multitude of layers of materials sensitive to hydrogen concentrations and temperature on the end of a light transparent lens located within the sensor probe. The end of the lens within the sensor probe contains a lens containing a layer of hydrogen permeable material which excludes other reactive gases, a layer of reflective metal material that forms a metal hydride upon absorbing hydrogen, and a layer ofmore » « less

Thin film hydrogen sensor

Patent Lauf, Robert J [Oak Ridge, TN]; Hoffheins, Barbara S [Knoxville, TN]; Fleming, Pamela H [Oak Ridge, TN]

A hydrogen sensor element comprises an essentially inert, electrically-insulating substrate having a thin-film metallization deposited thereon which forms at least two resistors on the substrate. The metallization comprises a layer of Pd or a Pd alloy for sensing hydrogen and an underlying intermediate metal layer for providing enhanced adhesion of the metallization to the substrate. An essentially inert, electrically insulating, hydrogen impermeable passivation layer covers at least one of the resistors, and at least one of the resistors is left uncovered. The difference in electrical resistances of the covered resistor and the uncovered resistor is related to hydrogen concentration inmore » « less

Method and system for producing sputtered thin films with sub-angstrom thickness uniformity or custom thickness gradients

Patent Folta, James A [2262 Hampton Rd., Livermore, CA 94550]; Montcalm, Claude [14 Jami St., Livermore, CA 94550]; Walton, Christopher [2927 Lorina St., #2, Berkeley, CA 94705-1852]

A method and system for producing a thin film with highly uniform (or highly accurate custom graded) thickness on a flat or graded substrate (such as concave or convex optics), by sweeping the substrate across a vapor deposition source with controlled (and generally, time-varying) velocity. In preferred embodiments, the method includes the steps of measuring the source flux distribution (using a test piece that is held stationary while exposed to the source), calculating a set of predicted film thickness profiles, each film thickness profile assuming the measured flux distribution and a different one of a set of sweep velocity modulationmore » « less
