  • Arrangements For Transmission Of Measured Signals (AREA)

Description

Дл  дистанционной передачи показаний измерительных стрелочных приборов, в частности циферблатных весов, примен ют след щие приставки , содержащие два фотоэлемента и источник света, между которыми находитс  стрелка измерительного прибора. Существенный недостаток приставок подобного рода состоит в их вли нии на измерительный прибор.For remote transmission of readings of measuring point instruments, in particular dial scales, use of the following consoles, containing two photocells and a light source, between which there is an arrow of the measuring instrument. A significant disadvantage of consoles of this kind is their effect on the measuring instrument.

В предлагаемой приставке оба фотоэлемента помещены р дом на ее стрелке. Такое выполнение приставки позвол ет освободить стрелку измерительного прибора от обычно располагаемых на ней зеркал и других элементов оптической системы, что обеспечивает устранение вли ни  след щей приставки на измерительный прибор.In the proposed prefix, both photocells are placed side by side on its arrow. Such an implementation of the device allows the arrow of the measuring device to be freed from mirrors and other elements of the optical system that are usually located on it, which ensures that the tracking device does not affect the measuring device.

На чертеже изображена схема предлагаемой приставки.The drawing shows the scheme of the proposed consoles.

Устройство представл ет собой след щую приставку, не св занную с механизмом весов и имеющую Г-образную стрелку 1, располагаемую соосно со стрелкой 2 прибора, показани  которого снимаютс . На стрелке / помещены два фотосопротивлени  (или фотоэлемента): задающее 3 и рабочее 4. Первое из них имеет посто нную освещенность, создаваемую осветителем 5, а освещенность второго определ етс  положением стрелки измерительного прибора. При разной освещенности фотосопротивлений с помощью системы усилителей происходит возбуждение обмоток электродвигател  6, привод щего в движение стрелку / след щей приставки до выравнивани  сопротивлений рабочего и задающего фотосопротивлений. Одновременно посредством сельсина-датчика 7 угол отклонени  стрелки передаетс  на индикатор весов. Дл  дистанционного управлени  работой весов след ща  приставка может быть закреплена против значени  шкалы 8, определ ющего взвешиваемую .дозу материала.The device is a following prefix that is not connected with the mechanism of the balance and has an L-shaped arrow 1 located coaxially with the arrow 2 of the instrument, the readings of which are taken. On the arrow / there are two photoresistances (or photo cells): defining 3 and working 4. The first of them has a constant illumination created by the illuminator 5, and the illumination of the second is determined by the position of the arrow of the measuring device. At different photoresistance illuminances, the windings of the electric motor 6 are driven by an amplifier system, setting the arrow / follower in motion until the working resistance and the setting photoresistance are equalized. At the same time, the deflection angle of the arrow is transmitted to the weighing indicator by means of the selsyn sensor 7. To remotely control the operation of the balance, the prefix can be fixed against a scale value of 8, which determines the material dose to be weighed.

Предмет изобретени Subject invention

След ща  приставка к стрелочным измерительным приборам, например весам, дл  дистанционной передачи их показаний, содержаща  два фотоэлемента и источник света, между которыми находитс  стрелка измерительного прибора, отличающа с  тем, что, с целью устра ,ени  вли ни  след щей приставки на измерительный прибор, оба фотоэлемента помещены р дом на стрелке приставки.A track attachment to a dial gauge, such as a scale, for remote transmission of readings, containing two photocells and a light source, between which there is a measuring instrument arrow, characterized in that, in order to eliminate the influence of the tracking pin on the gauge , both photocells are placed next to the prefix arrow.
