Cleaning and grinding of sulfite sensor head
View Patent ↗A sensor for detection and measurement of a particular substance present in a liquid is disclosed. The sensor includes a non-circular or non-symmetrically fixed electrode for detection and measurement of a particular substance present in a liquid in which said sensor is submersed. The sensor with non-circular or non-symmetrically fixed electrode and method of using the same reduces or eliminates electrode deformation upon residue removal therefrom thereby prolonging operating life.
1. A sensor for detection and measurement of a particular substance present in a liquid, comprising:
a base with an interior edge, an exterior edge and a top surface extending between the interior edge and the exterior edge;
a continuous non-circular or non-symmetrical electrode for varied distance of the continuous non-circular or non-symmetrical electrode from the interior edge and the exterior edge fixed on said top surface for detection and measurement of a particular substance present in a liquid in which said sensor is submersed, and
a rotating ceramic stone to periodically clean residue from the continuous non-circular or non-symmetrical electrode without formation of an electrode dual side-abutting groove in the rotating ceramic stone, wherein the electrode dual side-abutting groove simultaneously abuts each side of the continuous non-circular or non-symmetrical electrode, due to the continuous non-circular or non-symmetrical electrode's varied distance from the interior edge and the exterior edge.
2. The sensor according to claim 1 wherein said base is manufactured from plastic, glass or ceramic material.
3. The sensor according to claim 1 wherein said electrode is manufactured from a metal.
4. The sensor according to claim 1 wherein said electrode is manufactured from silver, gold, platinum or a combination thereof.
5. The sensor according to claim 1 wherein said particular substance is sulfite.
6. The sensor according to claim 1 wherein said liquid is water.
7. A method of using a sensor for detection and measurement of a particular substance present in a liquid, comprising:
submerging a sensor comprising a base with an interior edge, an exterior edge, a top surface extending between the interior edge and the exterior edge, and a continuous non-circular or non-symmetrical electrode for varied distance of the continuous non-circular or non-symmetrical electrode from the interior edge and the exterior edge fixed on said top surface, in a liquid for detection and measurement of a particular substance present in said liquid; and
periodically cleaning residue from the continuous non-circular or non-symmetrical electrode using a rotating ceramic stone without formation of an electrode dual side-abutting groove in the rotating ceramic stone, wherein the electrode dual side-abutting groove simultaneously abuts each side of the continuous non-circular or non-symmetrical electrode, due to the continuous non-circular or non-symmetrical electrode's varied distance from the interior edge and the exterior edge.
8. The method according to claim 7 wherein said base is manufactured from plastic, glass or ceramic material.
9. The method according to claim 7 wherein said electrode is manufactured from a metal.
10. The method according to claim 7 wherein said electrode is manufactured from silver, gold, platinum or a combination thereof.
11. The method according to claim 7 wherein said particular substance is sulfite.
12. The method according to claim 7 wherein said liquid is water.
