  • Publication number: 20140311212
    Abstract: A gas sensor includes a gas sensing element positioned at least partially within a body and exposed at a first end to measure a gas in contact with the first end. The gas sensing element defines an axial direction. A flange extends from the body in a direction transverse to the axial direction. The flange has a first side facing toward the first end and a second side facing toward a remote end of the gas sensor. An O-ring is configured to sealingly position the gas sensor within a bore. An insertion portion of the gas sensor is defined by a wall and configured to hold the O-ring. The wall of the insertion portion is spaced a distance from the body at an axial position of the O-ring to provide a gap therebetween.

  • Publication number: 20140290334
    Abstract: A measurement device and method for detecting the hydrocarbon content in gases includes: devices for subdividing an original gas stream into first and second measuring gas streams; first and reference gas units for producing first and second reference gas streams from a substream of the first and second measuring gas streams, respectively; two sensors for determining the content of hydrocarbon in the two measuring gas streams and generating a corresponding measurement results; and an evaluation unit for evaluating the measurement results of the two sensors. The first sensor is alternately fed the first measuring gas stream or the reference gas stream prepared by the first reference unit, and the second sensor is alternately fed the second measuring gas stream or the second reference gas stream prepared by the second reference gas unit. Because the two cycles are time-offset, a measurement value is continuously available.

  • Publication number: 20140290333
    Abstract: An outer tube and a rubber plug are swaged at two sites, a first swaged section located on the side of connections between contact fittings of a connector and leads and a swaged section located closer to an open end of the outer tube than the first swaged section, such that the inside diameter of a portion of the outer tube is greater than the inside diameter. This prevents reduction of the detection accuracy of a gas sensor because sealing properties can be enhanced by heavily swaging at the second swaged section than the first swaged section. Additionally, excessive force can be prevented on the connections and the leads by lightly swaging the first swaged section rather than the second swaged section. Thus, the disconnection between the connector and the leads can be prevented.
