Abstract
Изобретение относитс к гальванотехнике и может использоватьс дл автоматического измерени плотности тока при нанесении гальванических покрытий. изобретени - упрощение конструкции и увеличени точности измерени путем использовани в качестве выходного сигнала среднего значени напр жени на выходе операционного усилител . Устройство содержит операционный усилитель 2 и бесконтактный магниточувствительный первичный измерительный преобразователь (тороидальный трансформатор 1) с обмоткой обратной св зи, конец которой подсоединен к входу усилител 2, а начало - к заземленному концу обмотки питани , и обмоткой питани , начало которой через резистор 3 подключено к выходу операционного усилител 2, соединенному с входом заземленного блока 4 выделени среднего значени напр жени . Повышение точности предлагаемого устройства по сравнению с прототипом достигаетс за счет того, что один первый измерительный преобразователь , расположенный в гальванической ванне , из-за меньшего объема вносит меньшие - искажени электрического пол в электролите , а также из-за того, что показани устройства не завис т от напр жени питани и от величины потока насыщени сердечника . Упрощение устройства обеспечиваетс за счет выделени одного первичного преобразовател . 2 ил. сл сThe invention relates to electroplating and can be used to automatically measure current density when electroplating is applied. the invention simplifies the design and increases the measurement accuracy by using the average voltage value at the output of the operational amplifier as the output signal. The device contains an operational amplifier 2 and a contactless magnetically sensitive primary measuring transducer (toroidal transformer 1) with a feedback winding, the end of which is connected to the input of amplifier 2, and the beginning is to the grounded end of the power winding, and the power winding, the beginning of which through a resistor 3 is connected to an output of the operational amplifier 2 connected to the input of the grounded block for the allocation of the average voltage value. Improving the accuracy of the proposed device compared to the prototype is achieved due to the fact that one of the first measuring transducer located in the electroplating bath makes smaller because of the smaller volume - distortion of the electric field in the electrolyte, as well as due to the fact that t from the supply voltage and the saturation flux of the core. Simplification of the device is provided by separating one primary converter. 2 Il. cl
