Abstract: Methods, apparatuses, and systems for providing a position sensing component are disclosed herein. An example sensor assembly may comprise: a primary sensing device, a reference sensing device located in proximity to the primary sensing device; and a flue coupled with one of the primary sensing device and the reference sensing device to provide a pathway for a first gas in a first area to access the one of the primary sensing device and the reference sensing device. The one of the primary sensing device and the reference sensing device is coupled to the flue and is configured to determine a first concentration level of the first gas in the first area. The other of the primary sensing device and the reference sensing device is configured to determine a second concentration level of the first gas in a second area.

Abstract: Various methods and apparatuses are provided for monitoring and detecting gas leaks. A method of determining a gas leak with a sensor assembly is provided. The sensor assembly includes a primary sensing device and a reference sensing device. The method includes receiving, via the primary sensing device, a first oxygen concentration level reading of a given area. The method also includes receiving, via the reference sensing device, a second oxygen concentration level reading of the given area. The method further includes comparing the first oxygen concentration level reading and the second oxygen concentration level reading. Based on the comparison, the method still further includes causing a transmission of a signal that a gas leak is occurring in an instance in which the first oxygen concentration level reading and the second oxygen concentration level reading have a difference greater than a threshold difference. A corresponding gas detection apparatus is also provided.

Abstract: A sensor system having an analyte modulator, detector and a pump. The concentration of an analyte sample may be modulated at one time constant. The detector may have an output with a drift at another time constant. The one time constant may be shorter than the latter time constant. The latter time constant may be substantially removed from the detector output with a discriminator. A reservoir may receive high concentrations of analyte from the modulator, before analyte is forwarded to the detector and pump via analyte conveyance lines and valving. The modulation or pre-concentration of analyte in the sensor system may entail shorter times and smaller volumes than those needed by the detector. Such mismatches may be alleviated via accumulation of analyte in the reservoir prior to being forwarded to the detector.
