Abstract
Способ оптического контроля уровня прозрачной жидкости, заключающийся в направлении на прозрачный контейнер с жидкостью светового луча, сформированного источником излучения, и улавливании преломленного луча приемником, установленным на одном уровне с источником по другую сторону контейнера, отличающийся тем, что сформированный луч направляют на плоскопараллельную стенку контейнера под углом падения луча 30 - 60, а место установки приемника выбирают из соотношениягде Δl - расстояние от оптической оси луча до приемника по стенке контейнера;γ - угол падения сформированного луча на стенку контейнера;d - суммарная толщина прозрачных стенок контейнера, через которые проходит луч;D - расстояние между прозрачными стенками контейнера, через которые проходит луч;n- оптический показатель преломления материала прозрачных стенок контейнера;n- оптический показатель преломления контролируемой жидкости.A method for optical control of the level of a transparent liquid, which consists in directing a light beam formed by a radiation source to a transparent container with a liquid, and capturing the refracted beam by a receiver installed at the same level with the source on the other side of the container, characterized in that the formed beam is directed to a plane-parallel wall of the container at an angle of incidence of the beam of 30 - 60, and the location of the receiver is chosen from the ratio where Δl is the distance from the optical axis of the beam to the receiver along the container wall; γ is the angle of incidence of the formed beam on the container wall; d is the total thickness of the transparent container walls through which the beam passes ; D is the distance between the transparent walls of the container through which the beam passes; n is the optical refractive index of the material of the transparent walls of the container; n is the optical refractive index of the controlled liquid.
