摘要： A particulate sensor (1) includes an ion source (15) and a reference potential member (45). The particulate sensor (1) detects particulates S contained in a gas under measurement EG by means of ions CP. The ion source (15) includes a ceramic structure (100) having a ceramic laminate (101) and a discharge electrode member (110). The discharge electrode member (110) has an inter-layer portion (112A, 111) embedded between the layers of the ceramic laminate (101) and an exposed portion (112B) extending from the inter-layer portion (112A, 111) to a position outside the ceramic laminate (101). The discharge electrode member (110) generates the gaseous discharge between the reference potential member (45) and the exposed portion (112B) including one or more needle-shaped distal end portions (1125) upon application of a constant DC discharge potential PV2.

摘要： A particle detection system (1) includes a particle sensor (10) having a detection section (11) exposed to a gas under measurement EG. The particle sensor (10) includes an insulating member (121, 100), and a heater section (150, 105) for heating at least a portion of the gas contact surface (121s, 101s) of the insulating member (121, 100). The particle detection system (1) includes adhesive restraining energization means (225, 223, S4, S10) for heating the gas contact surface (121s, 101s) to an adhesion restraining temperature Td at which adhesion of the particles S to the gas contact surface (121s, 101s) is restrained as compared with the case where the heater section is not energized, wherein adhering particles SA which are particles adhering to the gas contact surface (121s, 101s) burn at the particle burning temperature Tb.

摘要： A thin plate member which has a groove portion recessed toward the inside in a radial direction with a gap interposed between the thin plate member and the outer surface of a site on the front end side of a main body section. At least one end of the thin plate member is joined to the outer surface of the main body section and is provided radially outside the site on the front end side of the main body section. A seal member is disposed in the groove portion and has elasticity due to resin. Since the gap functions as a heat-insulating layer and is interposed between the seal member and the main body section, heat conduction from the main body section, that is, heat conduction through a first pathway is reduced, and thus deterioration of the seal member due to heat is suppressed.

摘要： A water quality measurement device (100) includes a flow channel (130), an ion sensor having a responsive film portion whose surface is disposed in the flow channel (130), a glass-electrode-type sensor having a glass electrode whose surface is disposed in the flow channel (130), a drive section (115), a first opening-closing section, and a second opening-closing section. When a storage condition is satisfied, the water quality measurement device (100) puts the first opening-closing section in a first closed state and puts the second opening-closing section in a second closed state, thereby producing a state in which the surface of the responsive film portion and the surface of the glass electrode are present in a common closed space (135) whereby the closed space (135) is put in a wet state without the surface of the responsive film portion being immersed in the liquid.

摘要： A gas sensor (200) in which individual ones of connection terminals (30) have, at a rear end portion, a first connection portion (31) connected to a corresponding connector terminal (60). Individual ones of the connector terminals have, at an end portion on a side toward separator (40), a second connection portion (61) connected to the first connection portion. One of the first and second connection portions assumes the form of an insertion piece (61g), and the other assumes the form of a female portion (31g) into which the insertion piece is inserted. At least one of the insertion piece and the female portion has an elastic portion (31a). The insertion piece is fitted into the female portion, and the elastic portion thereby elastically bends, whereby the first and second connection portions are elastically connected.
