Description
Предлагаетс способ измерени скорости и направлени воздушного потока при помощи последовательно соединенных источника посто нного тока, гальванометра и двух пластинчатых электродов, между которыми помещают радиоактивное вещество , ионизирующее воздух.A method is proposed for measuring the speed and direction of an air stream using a series-connected direct current source, a galvanometer, and two plate electrodes, between which a radioactive substance ionizing air is placed.
Электрическа схема прибора дл осуществлени предлагаемого способа изображена на чертеже.The electrical circuit of the device for carrying out the proposed method is shown in the drawing.
Прибор состоит из металлического зонда, представл ющего собой две металлические пластинки 1 к 2, вл ющиес как бы пластинками конденсатора, включенными последовательно с источником посто нного тока 3 и гальванометром 4. К ручке-державке 5 зонда прикреплен кусочек радиоактивного вещества 6 (например, урановой смолки).The device consists of a metal probe, which consists of two metal plates 1 to 2, which are like capacitor plates connected in series with a source of direct current 3 and a galvanometer 4. A piece of radioactive substance 6 is attached to the handle-holder 5 of the probe (for example, uranium tar).
Величина ионизации, создаваема радиоактивным веществом 6 в воздухе , вл етс практически величиной посто нной. Поэтому количество ионов, успевших осесть на пластины 1 п 2 зонда, зависит от скорости движени воздуха и будет тем меньще, чем больше скорость движени воздуха.The amount of ionization generated by the radioactive substance 6 in the air is practically constant. Therefore, the number of ions that had time to settle on the plates 1 p 2 of the probe depends on the speed of the air and the smaller the speed of the air will be.
Если прибор протарировать в единицах скорости, то по тариро27 Свод. Выпуск 10, 1949 г.If the device is traded in units of speed, then by tariro27 Code. Issue 10, 1949
вочной кривой МОЖНО определ ть скорости движени потоков воздуха .The temporal curve CAN determine the speeds of air flow.
Прибором можно также замер ть направление движени воздушных потоков. При определенной посто нной скорости движени воздуха электрический ток в цепи гальванометра будет иметь максимальное значение в том случае, когда движение потока воздуха направлено от радиоактивного вещества к зонду; при обратном направлении потока воздуха ток в цепи гальванометра будет иметь минимальное значение.The device can also measure the direction of air flow. At a certain constant air velocity, the electric current in the galvanometer circuit will have a maximum value in the case when the air flow is directed from the radioactive substance to the probe; in the opposite direction of air flow, the current in the galvanometer circuit will be minimal.
