ABSTRACT:
A hydraulic cylinder unit which comprises a cylinder, a piston slidably inserted in the cylinder in a fluid-tight manner, and a piston rod connected to the piston at one end thereof and projected outwardly from the cylinder and which is operated to extend the piston rod by a fluid supplied under pressure into one chamber in the cylinder and to retract the piston rod by a mechanical force applied to the piston or piston rod (single-acting type) or by a fluid supplied under pressure into the other chamber in the cylinder (double-acting type) is used for lifting, transporting or displacing a material in various industries. In the use of such hydraulic cylinder unit, load in the axial direction of the unit is applied to the cylinder unit by a load or material carried on operated by the cylinder unit or the piston rod thereof and detection of such load is often required. This load is detected by a strain gauge mounted in the piston rod.
