摘要： A sensor element includes: an element body having a front end and a back end which are both ends in a longitudinal direction, a lateral face which is a face along the longitudinal direction, an outer lead section disposed on the lateral face; and a dense layer which covers part of the lateral face. The outer lead section has a first region which is covered at least in part by the dense layer. The first region contains zirconia. TM ratio is lower than 2, the TM ratio being a ratio Ht/Hm of a peak height Ht of T-phase to a peak height Hm of M-phase of zirconia in a Raman spectrum measured using Raman spectroscopy, and the dense layer has a thickness less than 11 μm.

Limiting current A as a limiting current when oxygen is pumped out from a periphery of the reference electrode to a periphery of the measurement-object-gas side electrode is 30 μA or lower, A×Ra as a product of a diffusion resistance Ra [/mm] of the reference-gas introduction space and the limiting current A is 50,000 or smaller.

摘要： Producing and tuning an integrated vessel control model to meet decarbonization goals includes loading an base performance model for a vessel and corresponding observed carbon emissions from the vessel resulting from a set of control inputs for the vessel. A decarbonization model also is selected. A new integrated performance model is computed within a digital twin of the vessel modeling new performance metrics resulting from the deployment of accessories in the decarbonization model, and the new metrics are compared to minimum performance standards for the vessel. When a performance metric fails to meet the minimum standard, a corresponding accessory is identified as impacting the failing performance metric and an adjustment is incrementally applied to the accessory until the failing performance metric is determined to meet the minimum standard. Then, the new integrated performance model is simulated to predict resulting carbon emissions which is stored in the new integrated performance model.

摘要： A sensor element (10) including: a measurement chamber (150); a pump cell (110) including a solid electrolyte (111), an inner electrode (113) exposed to the measurement chamber, and an outer electrode (112), the pump cell being configured to adjust an oxygen concentration in the measurement chamber; a diffusion resistance portion (151); and a detection cell (120) configured to measure a concentration of a specific gas in the measurement target gas after the adjustment of the oxygen concentration. The outer electrode is covered by a porous layer (114) and is disposed in a hollow space (10G) surrounded by a gas non-permeable dense layer 115, 118. The hollow space is in communication with an air introduction hole (10h) that is open on a rear side relative to the diffusion resistance portion. The outer electrode is exposed via the porous layer to air introduced through the air introduction hole.

摘要： A sensor element includes first to third chambers communicating sequentially from a gas inlet, voltages are intermittently applied across inner electrodes facing the respective chambers and a reference pump electrode to perform pumping of oxygen between a measurement gas and the reference pump electrode being in contact with a reference gas, thereby to reduce H2O and CO2 in the measurement gas into H2 and CO in the first chamber, to oxidize H2 into H2O in the second chamber, to oxidize CO into CO2 in the third chamber, and to identify a concentration of H2O and a concentration of CO2 based on a pumping-in current at the time when electromotive force between an inner electrode and the reference pump electrode during non-application of a voltage is maintained at a target value.

摘要： A particle sensor for detecting particles in a flow of a measuring gas for detecting soot particles in an exhaust gas channel of a burner or of an internal combustion engine. The particle sensor includes a device for generating or for supplying laser light, a device for focusing laser light, and a device for detecting or transferring thermal radiation. The particle sensor includes at least one optical access, which separates an area exposed to the measuring gas from an area facing away from the measuring gas not exposed to the measuring gas, the device for generating or supplying laser light and/or the device for detecting or for transferring thermal radiation being situated in the area facing away from the measuring gas, wherein the particle sensor removes a sub-flow from the measuring gas flow and supplies it to the laser focus and further fluidically shields the optical access from the sub-flow.

摘要： A gas sensor includes: a metal tubular body including a through hole allowing a sensor element to penetrate in an axial direction; and a powder compact being filled between an inner surface of the tubular body constituting the through hole and the sensor element, and sealing between both end portion sides of the sensor element. At least a range of a through hole inner surface to come into contact with the powder compact filled between the inner surface and the sensor element is a stripe-like recessed and projecting region in which projecting portions and recessed portions are alternately arranged in the axial direction and those portions extend along an inner circumferential direction of the tubular body. An interval between the projecting portions in the axial direction is 50 μm to 150 μm. The following expressions are satisfied, 0.3 μm≤Rz1≤10 μm, and Rz1/Rz2≥2.0.

摘要： A gas sensor includes a sensor element detecting a concentration of a specified gas, a housing on an inner periphery side of which the sensor element is disposed, a contact terminal contacting an electrode terminal provided to the sensor element, an insulator holding the contact terminal, a base end side cover fixed to a base end side of the housing and covering the insulator, and a disc spring disposed between the cover and the insulator and pushing the insulator toward a tip end side. The insulator has a base end side projecting portion projecting toward the base end side and has an outer periphery base end face, which faces toward the base end side around the base end side projecting portion. The disc spring has a circular body portion and claw portions that project from an inner peripheral edge of the circular body portion toward the base end side.
