Fluid pressure actuators indicator |
摘要 |
A fluid pressure actuator such as an hydraulic top link has an external indicator device for marking the position of the piston within the actuator cylinder. The indicator has a collar which clamps on to the piston rod and a finger which extends longitudinally along the outside of the actuator cylinder to provide a direct reading of the piston position. An indirect indication may be provided by linking the longitudinally extending finger to a spring loaded tape indicator, or to an indicator arm which moves angularly across a scale.
