Abstract: Various example embodiments described herein relate to an electrochemical gas sensor. The electrochemical gas sensor can include a sensor cap having one or more solid features disposed on a surface of the sensor cap. The electrochemical gas sensor can include a counter electrode configured to generate a gas during use of the electrochemical gas sensor. The electrochemical gas sensor can include a vent assembly adapted to release at least a portion of the gas generated at the counter electrode out from the electrochemical gas sensor. The vent assembly can include a vent conduit and a vent membrane that defines a passage for the gas to flow from an extended portion of the counter electrode, to the vent conduit, via the vent membrane, so as to be vented from the electrochemical gas sensor.

Abstract: A sensing device is provided. For example, a sensing device may include a conducting element, a DC voltage source, a voltage measuring device, a first switching circuitry to selectively connect the DC voltage source to the conducting element, and a processor that controls the first switching circuitry. The conducting element comprises first and second dissimilar materials arranged such that there is a first junction between the dissimilar materials and a second junction between the dissimilar materials. The processor controls the first switching circuitry to connect the DC voltage source to the conducting element to apply a DC voltage for a first period of time and to disconnect the DC voltage source to measure a voltage over a second period of time.

Abstract: A sensor assembly for monitoring gas concentration and a method of the same are provided. The sensor assembly includes a start-up sensor and a long-run sensor. The start-up sensor is characterized by a first power-on period and the long-run sensor is characterized by a second power-on period that is longer than the first power-on period. The sensor assembly also includes a controller in communication with the start-up sensor and the long-run sensor. The controller is configured to cause the start-up sensor and the long-run sensor to power on. The controller is further configured to power off the start-up sensor and monitor the gas concentration via the long-run sensor upon the expiration of the second power-on period. A corresponding method of monitoring gas concentration is also provided.

Abstract: Embodiments relate generally to systems and methods for identifying the concentration of an electrolyte. A method may comprise scanning a diagnostic micro-electrode of an electrochemical sensor using scanning voltammetry at a plurality of electrolyte concentrations; generating a variable set of readings from the first scanning voltammetry scan using a potential difference between a strong hydrogen adsorption peak and an oxide reduction peak and/or oxide formation peak at each of the plurality of electrolyte concentrations; and determining a correlation by plotting the variable set of readings and the plurality of electrolyte concentrations. In some embodiments, the method may comprise scanning a diagnostic micro-electrode of a second electrochemical sensor using scanning voltammetry, wherein the second electrochemical sensor has been employed; generating a second set of readings; and determining the electrolyte concentration of the electrolyte of the second electrochemical sensor by applying the determined correlation to the second set of readings.
