FIELD: analysis of materials.
SUBSTANCE: invention relates to material analysis and relates to an optical sensor for liquid analysis. Sensor comprises a central channel section disposed in a housing through which the liquid to be analysed flows, and a spectral analysis device comprising an infrared radiation source emitting a signal, which is received by a receiving device after it passes through the liquid to be analysed, a supporting plate, which supports the infrared source and the receiving device. Liquid to be analysed flows through a closed loop in the central section of the channel, formed by walls in the form of an arch of an optical component and a protrusion of the housing in the optical component. Gasket is sandwiched between the optical component and the housing and prevents the diffusion of liquid inside the housing.
EFFECT: technical result consists in providing the possibility of conducting continuous analysis of a liquid without the formation of a stagnant pocket and accumulation of precipitation.
