Disclosed is an infrared optical sensor for the continuous analysis of a liquid flowing in a pipe. The sensor includes, in a housing, a central section of duct through which the liquid to be analyzed flows, and a spectral analysis device using a light beam, including an infrared source which emits a signal which is received by a receiving device having passed through the liquid, an optical component which allows the light beam to pass through the liquid, and a support plate which carries the infrared source and the receiving device. The liquid to be analyzed circulates through a loop formed by walls in the form of an arch of the optical component and by a projection of the housing in the optical component. A sealing gasket is compressed between the optical component and the housing, in order to prevent any diffusion of liquid on the interior of the housing.
An optical sensor for the analysis of a liquid, wherein the sensor (100) comprises, in a housing (1), a central section of duct (2′) through which the liquid (3) flows, a spectral analysis device using a light beam (30) in a wavelength band emitted by an infrared source (22) and received by a receiving device (28), having passed through the liquid to be analyzed (3) via an optical component (9), and a support plate (13) arranged on a base (16) which carries the infrared source (22) and the receiving device (28), characterized in that the liquid to be analyzed (3) flows through a loop (4) in the central section of duct (2′) enclosed by walls of the optical component (9), which form an arch (50), in that the housing (1) forms a projection (60) in said arch (50), and in that a sealing gasket (10) is compressed between the optical component (9) and the housing (1), in order to prevent any diffusion of liquid on the interior of the housing (1).
