Description
Предметом изобретени вл етс фотоэлектрическое устройство дл определени степени белизны материалов . Описываемое ниже изобретение выполнено Б виде подвижной кассеты с образцами исследуемого и эталонного материалов, которые поочередно устанавливают под фотоэлементом .The subject of the invention is a photovoltaic device for determining the degree of whiteness of materials. The invention described below is made in the form of a movable cassette with samples of the test and reference materials, which are alternately placed under the photocell.
Белизна измер емого объекта определ етс по шкале гальванометра , отградуированного в процентах белизн1 1 дл естественного дневного или искусственного электрического освещени .The whiteness of the object to be measured is determined on the scale of a galvanometer, calibrated as a percentage of whiteness 1 for natural daylight or artificial electric illumination.
На чертеже изображена принципиальна схема устройства.The drawing shows a schematic diagram of the device.
Принцип работЕ предлагаемото прибора заключаетс в том, что в услови х достаточного освещени , естественного или искусственного, перфорированный фотоэлемент 1 освещаетс отраженным светом от эталона 2, имеющего 70% белизны.The principle of operation of the proposed device is that, under conditions of sufficient illumination, natural or artificial, the perforated photocell 1 is illuminated by reflected light from standard 2, which has 70% of whiteness.
Световой поток проходит через подвижную диафрагму 3, привод щу ос в движение приводным механизмом 4 при вращении руко ткой 5.The luminous flux passes through the movable diaphragm 3, which drives the axle into motion by the drive mechanism 4 when rotated by the handle 5.
Путем диафрагмировани электрический индикатор (гальванометр) 6,By means of a diaphragm, an electric indicator (galvanometer) 6,
св занный с фотоэлементом, устанавливают в положение, соответствующее ве,тичине белизны эталона, в данноМ случае 70%. После установки индикатора в указанное положение подвижна кассета 7 передвигаетс с таким расчетом, чтобы место эталона 2 зан л исследуемый образец 8.associated with the photocell, set to the position corresponding to the ve, the silence of the whiteness of the standard, in this case 70%. After the indicator is installed at the indicated position, the movable cassette 7 is moved so that the place of the reference 2 is occupied by the sample 8.
Белизна измер емого образца может быть црочтена на шкале индикатора , отградуированного в процентах белизНы.The whiteness of the measured sample can be measured on the indicator scale, calibrated as a percentage of whiteness.
Предмет изобретени Subject invention
Фотоэлектрическое устройство дл определени белизны материалов с использованием естественного или искусственного освещени , о т л ич а ю и; е е с тем, что оно выполнено в виде подвижной, кассеты с образцами исследуемого и эталонного материалов, поочередно устанавливаемыми под фотоэлементом, выполненным перфорированным и снабженным диафрагмой, служащей дл установки гальванометра на нулевое деление шкалы при данной освещенности и при установке под фотоэлементом образца эталонного материала .A photovoltaic device for determining the whiteness of materials using natural or artificial light, for example; This is so that it is made in the form of a movable cassette with samples of the test and reference materials, alternately installed under a photocell made perforated and equipped with a diaphragm, which serves to set the galvanometer to zero scale division at a given illumination and when the sample material is installed under the sample reference material .
