Claims

[Scope of utility model registration request]

A potentiometer for a hydropneumatic cylinder that detects the displacement of the piston of a hydropneumatic cylinder having a piston inserted into the cylinder and a piston rod connected to the piston by a change in the resistance value of a linear resistor, The piston rod is formed to be hollow, and a hollow rod is inserted into the piston rod so as to be relatively movable in the axial direction, and connected to the inner circumferential surface of the piston rod to a linear resistor along the axial direction and one end of the resistor. A conductor and a conductor connected to the other end of the resistor are fixed in parallel with the resistor, and contacts are attached to the tip of the rod to slide on the resistor and each conductor, respectively, and connected to each of these contacts and connected to the outside. A potentiometer for a hydraulic pneumatic cylinder, characterized in that each harness taken out from the rod is inserted into the rod.
