Изобретение относитс  к измерительной технике, а именно к устройствам контрол  уровн  электропроводных сред.The invention relates to a measurement technique, namely, devices for controlling the level of electrically conductive media.

По основному авт. св. № 263198 извест  о устройство дл  измерени  электропровод- ной жидкости, представл ющее собой элек- троконтактный блок, выполненный в виде двух, расположенный друг над другом неизолированных электродов, кинематически и электрически св занных с токоведущим тросом , сматываемым с барабана при помощи реверсивного электродвигател  остановкой и пуском которого управл ют два реле, расположенные в выходных цеп х усилителей тока.According to the main author. St. No. 263198 is aware of a device for measuring an electrically conductive liquid, which is an electrical contact unit made in the form of two, located one above the other uninsulated electrodes, kinematically and electrically connected to a current-carrying cable, unwound from the drum using a reversible electric motor and a stop the start of which is controlled by two relays located in the output circuits of the current amplifiers.

Однако разделение сигнала, проход щего через жидкость и электроды при их контакте , по величине (в цепи нижнего электрода включено добавочное сопротивление) и использование реле разной чувствительности в случае изменени  удельной электропроводности вызывает автоколебани  системы (сигнал меньщей величины может стать достато ным дл  срабатывани  реле более низкой чувствительности),However, the separation of the signal passing through the liquid and the electrodes when they are in contact is larger (additional resistance is switched on in the lower electrode circuit) and the use of relays of different sensitivity in the event of a change in conductivity causes auto-oscillations of the system (a smaller signal may become sufficient to trigger the relay low sensitivity),

Цель изобретени  - повышение надежности работы устройства при контроле сред с переменной удельной электропроводностью и расширение области применени . Это достигаетс  тем, что устройство снабжено тр& м  полупроводниковыми диодами, один из которых подключен катодом к нижнему электроду , анодом - к верхнему электроду и токо- ведущему тросу, а два других последовательно соединенных диода подключены к входам усилителей тока и к токоведущему тросу, один - анодом, другой - катодом.The purpose of the invention is to increase the reliability of the device while monitoring media with variable specific conductivity and expanding the scope. This is achieved by the fact that the device is equipped with a & m semiconductor diodes, one of which is connected by the cathode to the lower electrode, by the anode to the upper electrode and the current-leading cable, and the other two series-connected diodes are connected to the inputs of current amplifiers and to the current-carrying cable, the other.

На чертеже изображена функциональна  схема устройства дл  измерени  уровн ,The drawing shows the functional diagram of the device for level measurement,

Устройство имеет электроконтактный блок, состо щий из двух, расположенных друг над другом неизолированных электродов 1 и 2. В цепи нижнего электрода диод 3 анодом к верхнему электроду и несущему токоведущему тросу 4.The device has an electrocontact unit consisting of two uninsulated electrodes 1 and 2 arranged one above the other. In the circuit of the lower electrode, the diode 3 is an anode to the upper electrode and a carrier current-carrying cable 4.

Постранство между электродами залито герметиком. Несущий токопровод щий трос наматываетс  на барабан 5 реверсивным электродвигателем 6, Диоды 7 и 8 включены во входных цеп х усилителей тока 9 иThe space between the electrodes is filled with sealant. The carrying cable is wound on the drum 5 by a reversing motor 6, Diodes 7 and 8 are included in the input circuits of the current amplifiers 9 and
