Description
возникают интерференционные полосы (фиг. 3,а), наклон которых определ етс углами аир (фиг. 2 а, б),interference fringes appear (fig. 3, a), the slope of which is determined by the angles of the air (fig. 2 a, b),
При нагружении силовоспринимающей пластины силой F измен етс только угол Р, что приводит к изменению наклона интерференционных полос. Рассто ние между полосами практически остаетс посто нным . При помощи нескольких оптических систем 3 важные дл кодировани положени интерференционных полос отображаютс на фотоэлектрических приемниках 5 с последовательно подключенными ступен ми формовани импульсов.When a force-receiving plate is loaded with a force F, only the angle P changes, which leads to a change in the slope of the interference fringes. The distance between the lanes is almost constant. With the help of several optical systems, 3 important for coding positions of the interference fringes are displayed on photoelectric receivers 5 with successively connected pulse shaping stages.
На фиг. 3 примерно изображено расположение приемников дл трехдорожечного двоичного кода с У-зондированием. Места зондировани наход т, если приемники помещают в тех местах YI, YZ, УЗ , где происходит изменение пор дковых чисел 1; 2; 4.FIG. 3 shows roughly the location of receivers for a three-track binary code with Y-sounding. The probes are located if the receivers are placed in the places YI, YZ, UZ, where the change of the order numbers 1 occurs; 2; four.
Путем дальнейшего смещени приемников в этих У-местах параллельно оси X наход т правильное положение приемников в пределах кодируемой дорожки.By further shifting the receivers in these Y-locations parallel to the X-axis, the correct position of the receivers within the encoded track is found.
На фиг. 3,а изображен переход от кодового знака 7 к кодовому знаку 8. Этому переходу соответствует сила . При увеличении силы интерференционные полосы вращаютс вокруг точек на оси Х (фиг. 3,6), а дл Р Рмакс они проход т параллельно оси У (фиг. 3,6). Это положение соответствует переходу от знака кода 3 к кодовому знаку 4. Если же сила увеличиваетс до макс, то полосы вращаютс в положении, симметричном положению на выходе (фиг. 3,е).FIG. 3, and shows the transition from code mark 7 to code mark 8. This transition corresponds to the force. As the force increases, the fringes rotate around points on the X axis (Fig. 3.6), and for P Pmax they run parallel to the Y axis (Fig. 3.6). This position corresponds to the transition from the sign of code 3 to code sign 4. If the force increases to max, the bands rotate in a position symmetrical to the exit position (Fig. 3e).
Это положение соответствует переходу от кодового знака 7 к кодовому знаку 8. Путем симметричного изменени из интерференционной картины можно использовать максимальное количество интерференционных полос дл измерени .This position corresponds to the transition from code mark 7 to code mark 8. By symmetrically changing from the interference pattern, the maximum number of interference fringes can be used for measurement.
В зависимости от того, каким кодом производитс кодирование, на фотоэлектрических приемниках отобраз тс при помощи отдельных оптических систем определенные места вращающихс интерференционныхDepending on what code is used to encode, photoelectric receivers display certain areas of rotating interference using separate optical systems.

Corresponding steps of forming a pulse are sequentially connected to these receivers, at the outputs of which coded signs are obtained that correspond to measured magnitudes.
Одно из преимуществ указанного устройства заключаетс в том, чтонесколько пластин точно слипаютс , образу компактное целое. Этипластины или плиткимогут изготавливатьс серийно, и поэтому не требуетс производить юстировки положени пластин относительно друг друга. Этот компактный узел обладает высокой стойкостью к встр ске и вибрации, а также изменению температуры.One of the advantages of this device is that several plates adhere precisely to form a compact whole. These plates or tiles can be manufactured in series, and therefore no adjustment of the position of the plates relative to each other is required. This compact unit is highly resistant to shock and vibration, as well as temperature changes.
Деформаци гибкой пластины, ёызьтйема прилагаемой силой, непосредственно преобразуетс в кодированный выходной сигнал, соответствующий измеренной величине .The deformation of the flexible plate applied by the force is directly converted into a coded output signal corresponding to the measured value.
Если материалом дл силовосиринимающей пластины служит кварц, то дл измерени силы создаютс исключительно благопри тные услови , так как кварц малоIf quartz is used as a material for a silovirising plate, then extremely favorable conditions are created for measuring force, since quartz is small.

Путем специально созданной формы воздушного зазора образуютс распределени вращающихс полос, которые позвол ют производить кодирование при помощи всех видов периодических кодов.subject to temperature and relaxation phenomena. By means of a specially designed air gap shape, the distributions of the rotating bands are formed, which allow coding with all kinds of periodic codes.
