Description

Приборы дл  непрерывного автоматического контрол  качества очистки поверхности металлической полосы, содержащие р д датчиков , определ ющих загр знение в различных ее точках, и индикатор к этому прибору, известны. Однако указанные приборы не достаточно надежны в эксплуатации и, кроме того, в этих приборах требуетс  применение отдельных усилителей и индикаторов дл  каждого датчика.Instruments for continuous, automatic monitoring of the quality of the cleaning of the surface of a metal strip, containing a series of sensors that detect contamination at various points of the strip, and an indicator to this instrument, are known. However, these instruments are not sufficiently reliable in operation and, moreover, these instruments require the use of separate amplifiers and indicators for each sensor.

Дл  повышени  эксплуатационной надежности и обеспечени  работы прибора с одним усилителем и одним индикатором дл  любого количества датчиков, примен емых в приборе, между датчиками и усилителем включено устройство, выдел ющее из сигналов всех датчиков наибольший сигнал.To increase the operational reliability and ensure the operation of the device with one amplifier and one indicator, for any number of sensors used in the device, between the sensors and the amplifier is turned on a device that extracts the largest signal from the signals of all sensors.

На блок-схеме прибора изображен прибор, состо щий из блока одинаковых фотодатчиков 1, количество которых может быть разным, схемы выделени  наибольшего сигнала загр знени  2, усилител  3, индикатора 4 и источника питани  5.The block diagram of the device depicts a device consisting of a block of identical photosensors 1, the number of which can be different, the selection of the largest signal of contamination 2, amplifier 3, indicator 4 and power supply 5.

Каждый датчик состоит из лампы накаливани  - источника света и измерительного моста, трем  плечами которого  вл ютс  омические сопротивлени , а четвертым плечом - фотосопротивление. Все датчики питаютс  стабилизированным напр жением. Количество датчиков подбираетс  в зависимости от ширины контролируемой полосы.Each sensor consists of an incandescent lamp — a light source and a measuring bridge, the three arms of which are ohmic resistances, and the fourth shoulder is the photoresistance. All sensors are supplied with stabilized voltage. The number of sensors is selected depending on the width of the monitored band.

Схема выделени  наибольшего сигнала состоит из диодов, количество которых равно количеству датчиков, и сопротивлени  нагрузки, напр жение с которого подаетс  непосредственно на сетку усилительной лампы, Причем сопротивление нагрузки должно быть больше на два-три пор дка, чем выходное сопротивление датчика, а обра гное сопротивление диода на пор док больше сопротивлени  нагрузки.The selection circuit of the largest signal consists of diodes, the number of which is equal to the number of sensors, and the load resistance, the voltage from which is fed directly to the grid of the amplifying lamp. Moreover, the load resistance must be two to three orders of magnitude higher than the output resistance of the sensor, and the diode resistance is an order of magnitude greater than the load resistance.
