A gas sensor seal () comprising a body (), an upper portion having a flange (), and at least one channel (). The flange () has an extension () that extends from the upper portion, a bend () which extends from the extension () along the body (), and a protrusion () which extends from the bend () toward the body (). The channel () extends through the body () from the upper portion to a lower surface (). A method for using the gas sensor seal () within a sensor () is also provided.

Gas sensor seal and method of producing same

A gas sensor is created comprising an electrochemical cell having a solid electrolyte layer disposed between an exhaust gas electrode and a reference electrode. A resistor is disposed in electrical communication with a heater and the reference electrode. The resistor can be disposed on a side of the gas sensor; on a side of the gas sensor such that the resistor is electrically connected through a via hole; over at least a portion of at least two sides of the gas sensor; or disposed in a void extending at least from the heater to the pump electrode, such that the void extends to at least a surface of the gas sensor, extends to at least partially through the gas sensor, or extends completely through the gas sensor. A method for using this gas sensor comprises applying a voltage to the heater within the gas sensor. A current is directed through the resistor to the reference electrode to pump oxygen into the reference electrode.

Method and device for pumping oxygen into a gas sensor

An oxygen sensor includes an elongated planar sensing element and a lower insulator sealably mounted within a tubular shield. The sensing element extends through a central opening disposed in the lower insulator into a sensing chamber. An annular glass support bonded at an end of the insulator is in non-bonding contact with the sensing end of the sensing element. A portion of the sensing element adjacent the glass support is coated with a carbon-based ink to prevent bonding of the glass support to the sensing element. In an alternative, a metal foil support may extend between the sensing element and the glass support. The metal support includes a plurality of dimples disposed on opposing walls that extend inwardly to contact and non-bindingly support the sensing element therein.

Oxygen sensor

A sensor with a glass seal between a planar sensing element in a tubular housing and the tubular housing, wherein the glass seal is maintained in radial compression over an entire temperature operating range of the sensor. The compressed seal has improved strength and durability, is self-limiting and is operable over a large temperature range and in an environment subject to jarring and vibrations.

Sensor with glass seal

An oxygen sensor comprising: an elongated planar sensing element; a tubular shield within which at least a portion of the sensing element extends; a seal sealably mounting the sensing element within the tubular shield; a shell for mounting the oxygen sensor to a body through which exhaust flows; and an annular gasket seating at a first surface the tubular shield and at a second surface an annular seat of the shell, wherein there is no direct contact between the tubular shield and the shell. An advantage of improved shock resistance is obtained, preventing damage to the seal, which may be made of glass.

Oxygen sensor with annular support member providing improved mechanical

Disclosed is an exhaust oxygen sensor including a component requiring electricity to operate such as a heater or oxygen electrode. The first electrical terminal is provided in electrical contact with the component and wherein the electrical terminal has at least one male prong. The second electrical terminal in electrical contact with a wire for delivering electrical power from an external source is also provided. The second electrical terminal has at least one female connector or receptacle. The male prong and the female connector are constructed and arranged so at least one of the first and second electrical terminals is removable with respect to the other terminal. The sensor may include a threaded nut slidably received over a tubular housing, constructed and arranged to be threaded onto a threaded exhaust manifold boss without rotating the housing.

Exhaust sensor with removable electrical connector

An exhaust sensor having a substrate including first and second portions, the first portion comprising a dielectric material, the second portion comprising an electrolyte material and a transition zone interposed between the first and second portions. The transition zone includes an increasing concentration of the dielectric material in the direction of the first portion of the substrate and an increasing concentration of the electrolyte material in a direction towards the second portion of the substrate. The invention also includes a method of making such an exhaust sensor substrate including the steps of co-depositing first and second amenable compositions, the first composition comprising a dielectric material and the second composition comprising an electrolyte material. The co-deposited compositions are fired together to form the substrate having first, second and transition portions as described above. The two compositions may be co-deposited as a slurry and spread over a substrate using a partition doctor blade to form a very thin tape of a dielectric material and an electrolyte material. The two compositions may be co-deposited by feeding the compositions side by side through a compaction press to form a single tape having a first dielectric portion and a second electrolyte portion.

Exhaust sensor with tubular shell

A self heating, readily assembleable solid electrolyte oxygen sensor is provided. A heater subassembly readily adaptable to unheated oxygen sensor technology, provides the means for positioning and rigidly securing the heater element within the oxygen sensing device through the use of locating means on the heater element and corresponding locating projections on the electric connector terminals. The terminals also provide the means for electrically coupling the resistance heating wires of the heater element to the external ground and power signals.

Heated solid electrolyte oxygen sensor

A rotary indirect printing assembly for printing objects to be sequentially cycled past the assembly including a printing drum presenting a printing surface and a platform with the printing drum rotatably supported upon the platform. The assembly also includes a transfer roller presenting a transfer surface with the transfer roller rotatably supported upon the platform and rotating in time with the printing drum. The printing surface of the printing drum and the transfer surface of the transfer roller are in tangential rotational contact with respect to each other to transfer an ink image from the printing surface to the transfer surface to transfer the image to an object as an object is sequentially cycled past the assembly. The printing drum and the transfer roller are disposed vertically with respect to the platform.
