Abstract
Official abstract text for this publication.
An optical measuring device that measures one or more parameters indicating a state of a measured liquid, includes: a light source that irradiates light to the measured liquid; a light receiver that detects a measured light based on the light irradiated to the measured liquid; an optical component that is disposed on an optical path between the light source and the light receiver; and a heat source on the optical component and that has optical transparency and electrical conductivity.
First claim
Opening claim text (preview).
What is claimed is: 1 . An optical measuring device that measures one or more parameters indicating a state of a measured liquid, comprising: a light source that irradiates light to the measured liquid; a light receiver that detects a measured light based on the light irradiated to the measured liquid; an optical component that is disposed on an optical path between the light source and the light receiver; and a heat source on the optical component and that has optical transparency and electrical conductivity. 2 . The optical measuring device according to claim 1 , wherein the optical component comprises glass disposed at a boundary of a liquid tank in which the measured liquid flows, and the heat source comprises a film formed on a surface of the glass. 3 . The optical measuring device according to claim 2 , wherein the glass is T-shaped. 4 . The optical measuring device according to claim 1 , wherein the optical component comprises a lens, and the heat source comprises a film formed on a surface of the lens. 5 . The optical measuring device according to claim 4 , wherein the lens is disposed at a boundary of a liquid tank wherein the measured liquid flows. 6 . The optical measuring device according to claim 2 , wherein the film comprises an indium tin oxide (ITO) film. 7 . The optical measuring device according to claim 1 , wherein the optical component is disposed on both a light-source side and a light receiver side, and the heat source is formed for both the optical component disposed on the light-source side and the optical component disposed on the light receiving side. 8 . The optical measuring device according to claim 1 , wherein one of the one or more parameters is turbidity of the measured liquid. 9 . The optical measuring device according to claim 1 , wherein one of the one or more parameters is chromaticity of the measured liquid. 10 . The optical measuring device according to claim 2 , wherein the optical component comprises a lens, and the heat source comprises a film formed on a surface of the lens. 11 . The optical measuring device according to claim 3 , wherein the optical component comprises a lens, and the heat source comprises a film formed on a surface of the lens. 12 . The optical measuring device according to claim 3 , wherein the film comprises an ITO film. 13 . The optical measuring device according to claim 4 , wherein the film comprises an ITO film. 14 . The optical measuring device according to claim 5 , wherein the film comprises an ITO film.
