Description
Согласно изобретению предлагаетс прибор дл измерени степени белизны, с указанием этой степени непосредственно по шкале прибора.According to the invention, a device is proposed for measuring the degree of whiteness, indicating this degree directly on the scale of the device.
Прибор может быть применен дл контрол как готовых изделий, так и полуфабрикатов, например, хлопка , льна, целлюлозы, бумаги, красителей хлопчатобумажных тканей, различных эмульсий, суспензий и т. п.The device can be used to control both finished products and semi-finished products, for example, cotton, flax, cellulose, paper, dyes of cotton fabrics, various emulsions, suspensions, etc.
Сущность изобретени по сн етс чертежом.The invention is illustrated in the drawing.
Установка рабочего напр жени осуществл етс при помощи реостата 3. Величина напр жени измер етс вольтметром 4.The setting of the operating voltage is made with the aid of a rheostat 3. The magnitude of the voltage is measured by a voltmeter 4.
Белизна или отражающа способность исследуемого объекта 8 определ етс путем компенсации отраженного и диффузно-рассе нного света 2, измер емого фотоэлементом / до некоторой посто нной величины за счет изменени интенсивности источника света 2, т. е. измерение производитс косвенным способом по величине сопротивлени в цепи источника света 2.The whiteness or reflectivity of the object under study 8 is determined by compensating the reflected and diffuse-scattered light 2 measured by the photocell to a certain constant value by changing the intensity of the light source 2, i.e. the measurement is made indirectly by the magnitude of the resistance in the circuit light source 2.
Реостат 5 служит основным органом измерени . Сопротивление реостата 5 рассчитываетс так, что его равномерна щкала 6 при компенсации в приведенной схеме тока фотоэлемента / отражает степень белизны исследуемого объекта 8 непосредственно в процентах.The rheostat 5 serves as the primary measuring body. The resistance of the rheostat 5 is calculated in such a way that its uniform size 6 when compensated for in the photocell current scheme shown / reflects the degree of whiteness of the object under study 8 directly in percent.
Предмет изобретени Subject invention
Прибор дл измерени белизны или т. п. оптических свойств бумаги или иных материалов по интенсивности светового потока, отражаемой исследуемой поверхностью материала , измер емого фотоэлектрическим индикатором, с применением источника света, в цепь которого включено переменное градуированное сопротивление , отличающийс тем, что с целью выполнени шкалы переменного сопротивлени равномерной и градуированной в единицах белизны исследуемого материала сопротивление выполнено неравномерным .A device for measuring the whiteness or the like of the optical properties of paper or other materials according to the intensity of the luminous flux reflected by the surface of the material being measured, measured by a photoelectric indicator, using a light source whose circuit includes a variable graduated resistance, characterized in the scales of variable resistance are uniform and graduated in units of whiteness of the material under study; the resistance is uneven.
