Leak detection method for use with the pressure lines of a hydraulic or pneumatic machine, whereby pressure is measured over time and compared with stored reference pressure values to determine if a threshold is exceeded

摘要

Method involves use of pressure transducers for time monitoring of the pressure in the pressure lines of a machine. The measured pressures are transferred to an analysis machine where the measured pressure (PI) over time is compared with stored reference pressure values (PS) over a corresponding pressure cycle. The difference is calculated to determine if a preset value is exceeded.
