초록 ▼

An object of the present invention is to accurately detect concentrations of mixtures in a fluid. An internal electrode 23 is disposed on the inner side of an external electrode 22 coaxially with the external electrode 22, and a plurality of points in the length direction of the internal electrode 23 are supported by a casing 21 via supporting members 28a and 28b. The state of a fluid S passing through a passage 26 between the external electrode 22 and the internal electrode 23 is detected based on electrostatic capacitance between the external electrode 22 and the internal electrode 23.

1. A fluid quality sensor for measuring mixture fluid comprising: a tubular casing having a first end and a second end and extending in an axial direction from the first end to the second end;a tubular external electrode disposed in an interior space defined by the tubular casing;an internal electrode disposed in an interior space defined by the external electrode, the internal electrode being positioned apart from and coaxially with the external electrode, a first passage being formed between an inner surface of the external electrode and an outer surface of the internal electrode;a pair of first members engaged with the external electrode in the axial direction, each of the first members including an electrical insulator;a pair of second members engaged with the pair of the first members, respectively, in the axial direction, each of the second members including at least one hole extending in a radial direction through the respective second member; each of the second members being engaged with an inner surface of the tubular casing in a radial direction, thereby preventing the second members from moving in the radial direction relative to the tubular casing, each of the second members including an electrical conductor;at least one supporting member connecting a surface of the at least one hole defined in each of the second members and the outer surface of the internal electrode, the at least one support member including an electrical conductor;an annular intake part engaged with the first end of the tubular casing in the axial direction, a second passage being formed in the annular intake part; andan annular outlet part engaged with the second end of the tubular casing in the axial direction, a third passage being formed in the annular outlet part,wherein concentration of a fluid passing from the second passage through the first passage to the third passage is detected based on electrostatic capacitance between the external electrode and the internal electrode. 2. The fluid quality sensor for measuring mixture fluid according to claim 1, wherein the internal electrode has two ends extending along the second and third passages respectively, and cross-sectional areas of the second passage and the third passage are equal to that of the first passage. 3. The fluid quality sensor for measuring mixture fluid according to claim 2, wherein both of the two ends of the internal electrode are cone-shaped, and the second and third passages of the intake and outlet parts are tapered along the cone-shapes of the two ends of the internal electrode respectively. 4. The fluid quality sensor for measuring mixture fluid on according to claim 3, wherein an angle of the cone shape of each of the two ends of the internal electrode ranges from 10° to 60°. 5. The fluid quality sensor for measuring mixture fluid according to claim 1, wherein at least two points on an outer surface of the internal electrode are attached to the casing by the supporting members. 6. The fluid quality sensor for measuring mixture fluid according to claim 1, wherein the second members are engaged with the intake or outlet part in the axial direction, thereby preventing the external electrode, each of the first members and each of the second members from moving in the axial direction. 7. The fluid quality sensor for measuring mixture fluid according to claim 1, wherein a temperature sensor is connected to the external electrode. 8. The fluid quality sensor for measuring mixture fluid according to claim 1, wherein the pair of the second members are engaged with the first and second ends of the internal electrode, respectively, each of the second members being engaged with one of the first and second ends via four supporting members, thereby fixing the internal electrode relative to the tubular casing. 9. The fluid quality sensor for measuring mixture fluid according to claim 1, wherein the at least one supporting member is engaged with the surface of the at least one hole of each of the second members on one side of the supporting member and engaged with the outer surface of the internal electrode on an opposing side of the supporting member, thereby restricting the internal electrode from moving in the radial direction relative to the tubular casing. 10. The fluid quality sensor for measuring mixture fluid according to claim 1, wherein the internal electrode is connected to the tubular casing via the pair of the second members and the supporting members that support the respective second members. 11. The fluid quality sensor for measuring mixture fluid according to claim 1, wherein each of the supporting members is sandwiched between the respective second member and the internal electrode.
