Abstract

Объектом данного изобретения является устройство для измерения положения поршня (2) в цилиндре (1), расположенном вдоль оси, которое содержит, по меньшей мере, два датчика (3, 4) положения, которые соответственно содержат: первый элемент (20, 40) датчика, неподвижно соединенный с опорной площадкой (31), соединенной с поршнем (2), второй элемент (10, 30) датчика, неподвижно соединенный с цилиндром (1), при этом первый и второй элементы каждого датчика выполнены с возможностью поступательного перемещения один относительно другого вдоль оси, параллельной оси цилиндра (1). Устройство характеризуется тем, что первые элементы (20, 40) датчика неподвижно соединены с одной и той же крепежной площадкой (31), которая соединена с поршнем (2) с помощью шарового соединения (50). Благодаря устройству, соответственно данному изобретению, датчик положения можно располагать в цилиндре таким образом, что на него не передаются поперечные усилия, действующие на поршень, в то время как поршень остается свободным в вращении вокруг оси цилиндра.
