Description
В и св зи 7. В другом крайнем отсеке, отгороженном перегородкой 2, размещен приемный замкнутый магнитонровод 8 с обмоткой 9. В средней чаети корпуса, отделенной с обеих сторон от остальных частей датчнка нерегородкамн 2, находитс нлата 10, на которой .смонтирована схема ciiHхронного детектора, состо ндего из четырех диодов И, четырех резисторов 12 и конденсатора 13. Дноды, как н во всех синхронных детекторах, включены в кольцо, к одной наре диагональных точек которого нодсоединина выходна обмотка; наралле.чьно выходной обмотке последовательно включено два резистора 12, н два резнстора , соединенных последовательно, нодключены к другой наре диагональных точек диодного кольца.B and connection 7. In the other extreme compartment, fenced off by partition 2, a receiving closed magnetic circuit 8 with a winding 9 is placed. In the middle part of the case, separated on both sides from the remaining parts of the sensor, non-urban 2, is mounted on the cii-synchronous circuit. detector, the state of four diodes And, four resistors 12 and a capacitor 13. Dnoda, as n in all synchronous detectors, are included in the ring, to one nara diagonal points which connect the output winding; In parallel to the output winding, two resistors 12 are connected in series, and two resistors connected in series are connected to the other diagonal points of the diode ring.
Последн пара св зана с выходом датчика , к которому параллельно иодсоедннен конденсатор 13.The last pair is connected to the output of the sensor, to which the capacitor 13 is parallel to the one connected to one another.
Работает датчик следующим образом.The sensor works as follows.
Электрический ток, нротека по обмотке 6, создает электрический ток в витке пз провод щей жидкости 4, причем величина последнего определ етс электропроводностью жидкости. Ток в жидкости, проход через центральное отверстие приемного маггшпонровода 8, создает -в нем переменный магнитный НОТОК, который, в свою очередь , нндуктирует в выходной обмотке 9 JДC, пропорциональную электропроводностн жидкости. Выходное напр женне обмоткн 9 нодаетс на диодное кольцо синхронного детектора. На синхронный детектор постунает в качестве онорното напр жснне с обмотки 7 св зи.An electric current, across the winding 6, generates an electric current in a turn pz conductive liquid 4, the magnitude of the latter being determined by the electrical conductivity of the liquid. The current in the fluid, the passage through the central opening of the receiving magpreter 8, creates in it a variable magnetic SUMMER, which, in turn, induces in the output winding 9 JDC, proportional to the electrical conductivity of the fluid. The output winding 9 is connected to the diode ring of the synchronous detector. On the synchronous detector, it will act as an on-line voltage from the winding 7 of the connection.
Устройство обеспечивает высокую точность и чувствительность измерений за счет эффективного подавлени электростатических на-водок.The device provides high accuracy and sensitivity of measurements due to the effective suppression of electrostatic in-vodka.
