Patent ID: 8905720

Claim:
An arrangement for monitoring a hydraulic pump within a platform, the arrangement comprising: a sensor arranged to generate sample values relating to a fluid characteristic variable, wherein a fluid is fed by the hydraulic pump within the platform; and a processor arranged to receive a plurality of the sample values from said sensor, wherein the processor is arranged to generate an absolute value of a difference between each of said received plurality of sample values and a subsequent associated sample value, wherein said received sample values are generated during a predetermined time period, and wherein the processor is arranged to determine an indication number corresponding to a number of said generated absolute values during the predetermined time period which are greater than a predetermined threshold value, wherein the processor is arranged to generate a piece of indication information depending upon a result of a comparison between said determined indication number and a predetermined comparison value, wherein the fluid characteristic variable comprises hydraulic fluid flow, and wherein the difference between each of said received plurality of sample values and the subsequent associated sample value is the difference between two directly successive sample values.
