Abstract (en)
[origin: WO2009148376A1] Device and method for sensing a parameter related to a position of a displaceable element (2) which is movable in an axial direction inside a housing (1) of a rock drilling machine, wherein said device includes a sensor element (4) which is located in a housing part. The sensor element (4) is an RF sensor element which is positioned adjacent to, along and sideways of a path of movement of the displaceable element (2). The invention also concerns a sensor element and a rock drilling arrangement.
