Abstract
An arrangement for monitoring a supply within a platform. A sensor is arranged to generate sample values relating to a fluid characteristic variable, wherein the fluid is fed by the supply within the platform. A processor is arranged to receive a plurality of sample values from the sensor. The processor, is arranged to generate an absolute value of a difference between each of the received plurality of sample values and a subsequent associated sample value, wherein the received sample values are generated during a predetermined time period. The processor is arranged to determine an indication number corresponding to the number of the generated absolute values which are greater than a predetermined threshold value. The sample collecting process is only active when a criterion comprising a stable pump in a no load condition and all hydraulic consumers are in a resting position or close to a resting position is fulfilled. The processor is arranged to generate a piece of indication information depending upon a result of a comparison between the determined indication number and a predetermined comparison value.
