Изобретение относитс -к измерител11ной технике и может быть использовано дл измерени перемещени тел -в плоскости из некоторого центрального положени ,в периферийное и обратно .The invention relates to a measuring technique and can be used to measure the movement of bodies in the plane from a certain central position to the peripheral one and vice versa.

Известно устройство дл измерени перемещений, содержащее нечетное Число датчиков, например смесь идентичных датчиков типа сопло-сопло, одий из которых - центральный, и два других расположены на оси устройства на рассто нии друг от друга, а четыре остальных датчика расположены симметрично оси устройства и перпендикул ра к ней и к оси централь-ного датчика-, и подвижный .экран с торцовой кромкой дл взаимодействи с датчиками, установленный с возможностью перемещени нормально ос м датчиков, кромка экрана расположена перпендикул рно оси устройства.

The length of the edge edge is greater than or equal to the diameter of the jets of the Sensor. Four sensors and directions not along the device (side sensors) are located From the central sensor, as well as axial sensors, at a distance i, measured along the lateral direction of movement located to the sensor axis at an angle at 1.

Таким образом, боковые датчики от центрального датчика отсто т на рассто ние 6 , а от оси устройства - на рассто ние Eswal. При перемещении экрана вдоль оси устройства диапазон измеренных перемещений равен диаметру струй датчика, что и опре10 дел ет диапазон измерени устройства в целом.Thus, the side sensors from the central sensor are spaced 6, and from the device axis, the distance Eswal. When moving the screen along the axis of the device, the range of measured displacements is equal to the diameter of the sensor jets, which determines the measurement range of the device as a whole.

Недостатком известного устройства вл етс низкий диапазон, измерений.A disadvantage of the known device is the low measurement range.
