ABSTRACT:
The present invention relates to a system for determining axial displacement of a rod forming part of a device comprising a member in which are formed at least two chambers containing high-pressure fluid and each defined by a respective surface portion of the rod. The system consists in forming a sliding coupling between the rod portion separating the two chambers and the seat in which the rod slides; in forming, on the aforementioned rod portion, a pair of annular grooves defining an annular surface portion; in forming at least a housing on the aforementioned member; and in fitting inside the housing a proximity transducer for determining displacement of the annular surface portion parallel to the rod.
