Description

Известны приборы дл  измерени  объема тел неправильной геометрической формы, основанные на измерении объема тела по объему вытесненной :им жидкости. Такие приборы могут быть выполнены в виде неподвижного сосуда с посто нным уровнем жидкости и электрического указател . Однако точность таких приборов недостаточна.Instruments are known for measuring the volume of bodies of irregular geometrical shape, based on measuring the volume of a body by the volume of the fluid displaced by it. Such devices can be made in the form of a fixed vessel with a constant level of liquid and an electric pointer. However, the accuracy of such devices is insufficient.

В описываемом приборе дл  повышени  точности измерений и ускорени  процесса измерений, электрический указатель уровн  помещен в отдельной трубке, сообщающейс  с сосудом дл  измер емого тела, а бюретка дл  отсчета объема выполнена перемещающейс  по вертикальной штанге.In the described device for improving the measurement accuracy and speeding up the measurement process, the electric level indicator is placed in a separate tube communicating with the vessel for the body to be measured, and the burette for reading the volume is made moving along the vertical rod.

На чертеже изображена схема описываемого прибора.The drawing shows a diagram of the described device.

ПрИбор состоит из неподвижного сосуда 1 с жидкостью 2, например денатурированным спиртом, стакана 3, вставл емого в сосуд бюретки 4 со шкалой 5, вертикальной штанги 6, по которой посредством втулки 7 перемещаетс  бюретка, резиновой трубки 8, соедин юш;ей сосуд и бюретку, и электрического указател  5, наход щегос  в трубке 10, сообщающейс  с сосудом.The instrument consists of a stationary vessel 1 with liquid 2, such as denatured alcohol, a glass 3, inserted into a vessel of a burette 4 with a scale of 5, a vertical rod 6 along which the burette, a rubber tube 8, connects the vessel through the sleeve 7, connects the vessel and the burette and an electric pointer 5 located in the tube 10 communicating with the vessel.

Дл  измерени  объема бюретку 4 поднимают вверх, а иглу 11 указател  9 перемещают таким образом, чтобы ее конец касалс  уровни жидкости 2 в трубке 10. При этом по электрической цепи проходит ток, и стрелка гальвано.метра отклон етс . После этого посредством винта бюретку 4 перемешают вниз до тех пор, пока электрическа  цепь не разомкнетс , так как жидкость 2 из сосуда / и трубки 10 уходит в бюретку 4, и ее уровень в трубке /Опонижаетс . Последующим вращением- винта 13 в обратную сторону бюретку 4 поднимают до тех пор, пока цепь снова не замкнетс , что отмечаетс  гальванометром 12.To measure the volume, the burette 4 is lifted upward, and the needle 11 of the pointer 9 is moved so that its end touches the levels of liquid 2 in the tube 10. In this case, a current flows through the electrical circuit and the arrow of the galvano meter is deflected. After that, by means of the screw, the burette 4 is stirred down until the electrical circuit is opened, as the liquid 2 from the vessel / and the tube 10 goes to the burette 4, and its level in the tube / is lowered. Subsequent rotation of the screw 13 in the reverse direction, the burette 4 is lifted until the circuit is closed again, as indicated by the galvanometer 12.

Соответствующее деление шкалы 5 принимаетс  за нулевую отметку , затем в стакан 3 укладываетс  тело 14, объем которого опреде№ 150657- 2 л етс . Повтор ютс  вышеописанные манипул ции с опусканием и подъемом бюретки 4, и по разности второго и первого показаний на шкале 5, проградуированной в,единицах объема, производитс  определение объема тела 14. При включении прибора в цепь переменного тока дл  его выпр млени  служит выпр митель 15. Величина тока в цепи ограничиваетс  сопротивлени ми 6.The corresponding division of the scale 5 is taken as the zero mark, then the body 14 is placed in the cup 3, the volume of which is determined by the number 150657-2. The above-described manipulations with the lowering and raising of the burette 4 are repeated, and the difference in the second and first readings on a scale of 5, scaled in units of volume, determines the volume of the body 14. When the device is switched to the AC circuit, the rectifier 15 serves to straighten it. The magnitude of the current in the circuit is limited by the resistances 6.

Описываемый прибор позвол ет упростить методику измерени  объема тел неправильной формы и повысить точность измерений.The described device allows us to simplify the method for measuring the volume of bodies of irregular shape and to improve the measurement accuracy.
