Description

Предлагаетс  устройство дл  непрерывного измерени  концентрации растворов по их электропроводности.A device is proposed for continuously measuring the concentration of solutions by their electrical conductivity.

Известные устройства того же назначени , состо щие из замкнутой кольцевой трубки, через которую непрерывно протекает исследуемый раствор, питающего и дифференциального трансформаторов, сердечники которых охватываютс  указанной трубкой, образующей контур св зи, и электрического измерительного прибора, подключаемого к выходу дифференциального трансформатора, не обеспечивают возможности получени  шкалы прибора, пропорциональной концентрации раствораВ описываемом устройстве этот недостаток устранен применением сельсина в качестве источника компенсирующего переменного напр жени , что дает возможность получени  щкалы прибора, пропорциональной значени м концентрации раствора.The known devices of the same designation, consisting of a closed annular tube through which the test solution flows continuously, supply and differential transformers, the cores of which are covered by the specified tube forming a communication loop, and an electrical measuring device connected to the output of the differential transformer do not provide obtaining a scale of the instrument proportional to the concentration of the solution in the device described, this disadvantage is eliminated by using a selsyn as compensating an alternating source voltage that allows the preparation schkaly instrument proportional to values of the solution concentration.

На чертеже изображена принципиальна  схема описываемого устройства .The drawing shows a schematic diagram of the described device.

Трансформатор 1 (см. схему) наводит в жидкостном контуре 2 э.д.с., создающую ток, величина которого зависит от концентрации электролита . Измерение тока осуществл етс  компенсационным способом с помощью дифференциального трансформатора 3. Кроме жидкостных ампервитков магнитопровод трансформатора 3 возбуждаетс  током, текущих в компенсационном контуре с сельсином 4.Transformer 1 (see diagram) induces in the liquid circuit 2 emf, creating a current, the value of which depends on the concentration of electrolyte. The measurement of the current is carried out by a compensation method using a differential transformer 3. In addition to liquid vortexes, the magnetic circuit of the transformer 3 is excited by a current flowing in the compensation circuit with selsyn 4.

Ампервитки возбуждени  от тока через жидкость и компенсациунные ампервитки направлены навстречу друг другу. Вторична  обмотка дифференциального трансформатора 3 подключена к электронному усилителю , работающему в режиме нулевого органа. При изменении электропроводности раствора на входе усилител  по витс  сигнал ощибки и реверсивный двигатель 5, включенный на выходе усилител , начнет перемещать ротор сельсина до тех пор, пока не наступит электромагнитное равновесие.Ampervite excitation from the current through the liquid and compensatory amp revitations are directed towards each other. The secondary winding of the differential transformer 3 is connected to an electronic amplifier operating in zero-organ mode. When changing the conductivity of the solution at the amplifier input, the error signal and the reversing motor 5, which is switched on at the amplifier output, will begin to move the selsyn rotor until electromagnetic equilibrium occurs.
