Description

Изобретение может быть нспользовано дл  непрерывного измерени  уровн  электропроводных жидких и сыпучих материалов.The invention may be used to continuously measure the level of electrically conductive liquid and bulk materials.

Известен способ непрерывного измерени  уровн  электропроводного материала, например , с помощью электродного датчика, погружаемого в емкость с материалом.A known method for continuously measuring the level of an electrically conductive material, for example, using an electrode sensor, is immersed in a container of material.

Недостатком известного способа, основанного на измерении омического сопротивлени  материала,  вл етс  невысока  точность измерени , обусловленна  вли нием изменени  электропроводности материала.A disadvantage of the known method based on measuring the ohmic resistance of a material is the low measurement accuracy due to the effect of a change in the electrical conductivity of the material.

Дл  повышени  точности измерени  по предлагаемому способу по длине датчика распредел ют электрический потенциал, а уровень материала определ ют по величине напр жени  между нижним концом датчика и стенкой емкости.To improve the measurement accuracy of the proposed method, the electric potential is distributed over the sensor length, and the material level is determined from the voltage between the lower end of the sensor and the vessel wall.

На чертеже показана схема, реализующа  описываемый снособ, где 1 - емкость, заполненна  электропроводным материалом 2, в который погружают . электродный датчик 3. К концам датчика подведено стабилизированное напр жение от источника питани  4, которое распредел етс  по всей длине датчика. И.меоитель напр жени  5, градуированный вThe drawing shows a circuit that implements the described snoos, where 1 is a capacitor filled with electrically conductive material 2 into which it is immersed. electrode sensor 3. A stabilized voltage is supplied to the ends of the sensor from a power source 4, which is distributed along the entire length of the sensor. I.Model voltage 5, graded to

единицах уровн , подключают к нижнему концу датчика 3 и стенке емкости 1.units of level, connected to the lower end of the sensor 3 and the wall of the container 1.

Измерение уровн  осуществл ют следующим образом. При отсутствии в емкости 1 материала 2 напр жение между нижним концом датчика 3 и стенкой емкости 1, контролируемое измерителем напр жени  5, равно нулю . По мере погружени  датчика 3 в материал 2 стенки емкости 1 оказываютс  подключенными через материал к участкам датчика со все возрастающим относительно его нижнего конца потенциалом.The level measurement is carried out as follows. In the absence of material 2 in the tank 1, the voltage between the lower end of the sensor 3 and the wall of the tank 1, controlled by the voltage meter 5, is zero. As the sensor 3 is immersed in the material 2, the walls of the container 1 are connected through the material to the potential of the sensor with increasing potential relative to its lower end.

Напр жение между стенками емкости 1 и нижним концом датчика 3 измен етс  пропорционально уровню материала 2.The voltage between the walls of the container 1 and the lower end of the sensor 3 varies in proportion to the level of material 2.
