Abstract

A method and system for determining the actuating pressure of a servo cylinder that is actuated by pressurized fluid. The actuation displacement of the servo cylinder is obtained from a sensor or other device. A pressure sensor measures inflow pressure at one point of a pressurized fluid line supplying the servo cylinder. The actuating pressure is determined based on the inflow pressure and the change in the actuation displacement of the servo cylinder.
