ABSTRACT:
A fluid-pressure actuated piston/cylinder assembly having a sensor capable of reading at least one indicia marking on a piston rod in order to determine the movement and specific location of the piston rod and cylinder relative to each other. The sensor is housed within a sealing gland that is incorporated into the piston/cylinder assembly and is isolated from the fluid pressure and external elements outside of the assembly. The method of providing a compact, accurate position detecting system for the noted piston/cylinder assembly is also set forth.
