ны с соответствующими электродами, образующими систему отсчета, а крайний отвод от делител  соедин етс  со сплошным электродом . В зависимости от величины приложенного к делителю напр жени  пороговые значени  возникают на тех или иных отводах делител . При этом на электродах, где напр жение равно или превышает пороговое значение , происходит рассе ние света. Плотность тока, протекающего через жидкокристаллическое вещество, составл ет несколько микроампер на 1 см, что .говорит о высоком входном сопротивлении вольтметраиндикатора . Прибор может работать как на отражение света, так и на просвет. В первом случае нижний электрод  вл етс  отражающим, во втором - прозрачным. Формула изобретени  1.Вольтметр-индикатор, содержащий циферблат , делитель напр жени  и чувствительный элемент, выполненный в виде двух пластин с нанесенными на них электродами, между которыми заключен слой жидкого кристалла , отличающийс  тем, что, с целью получени  непосредственного отсчета измер емой величины, циферблат выполнен в виде набора прозрачных токопровод щих электродов с нанесенными числовыми величинами. with the corresponding electrodes that form the reference system, and the extreme retraction from the divider is connected to a solid electrode. Depending on the magnitude of the voltage applied to the voltage divider, threshold values occur at various branches of the divider. At the same time, light is scattered on the electrodes, where the voltage is equal to or exceeds the threshold value. The density of the current flowing through the liquid crystal substance is several microamperes per cm, which indicates a high input resistance of the indicator voltmeter. The device can work as a reflection of light, and on the light. In the first case, the lower electrode is reflective, in the second - transparent. Claim 1. Voltmeter-indicator containing dial, voltage divider and sensitive element, made in the form of two plates with electrodes deposited on them, between which a layer of liquid crystal is enclosed, characterized in that in order to obtain a direct reading of the measured value, The dial is made in the form of a set of transparent conducting electrodes with applied numerical values. 2.Вольтметр-индикатор по п. I, отличающийс  тем, что, с целью упрощени  конструкции и технологии изготовлени , а также улучшени  нагл дности индикации, знаки циферблата выполнены в виде непровод щего пол .2. The voltmeter indicator according to claim I, characterized in that, in order to simplify the design and manufacturing technology, as well as to improve the indicativeness of the display, dial signs are made in the form of a non-conductive floor. fSOfSO И i LL f L LL J - U- -- UAnd i LL f L LL J - U- - U I i-,-I t -I L,,-i L.J L.-,-I , I i -, - I t -I L ,, - i L.J L .-, - I, тt гg т т t t i i
