Abstract
A combination for accurately determining the position of the movable part of a piston-cylinder device relative to the fixed part includes a long stroke position transducer movable in the operating direction of the device; a structure movable with the piston-cylinder device and which has a part extending in the operating direction; two position transducers positioned side-by-side and their direction of movement is normal to the operating direction. The movable parts of the two position transducers bear against the part of the structure. If there is no tilting of the piston within the cylinder, then electrical signals from the two position transducers remain unchanged, but the signals are changed if the piston tilts within the cylinder.
