Controller for a milking plant, computer-implemented method, computer program and non-volatile data carrier

A computer-implemented method for monitoring pressure levels in a milking plant, which method is performed in a processing unit of a controller, the method comprising:

• obtaining at least one pressure signal from at least one pressure sensor device in the milking plant during pressurization of the milking plant, the at least one pressure signal representing a function of time defining at least one measured pressure signature describing how a pressure level is developed over time in at least one component of the milking plant,
• comparing the at least one measured pressure signature to at least one reference pressure signature for said at least one component, which at least one reference pressure signature represents at least one pressure signal obtained from the at least one pressure sensor device during pressurization of the milking plant when the milking plant is tuned to fulfil at least one quality condition with respect to said at least one component, and
• generating at least one alarm if at least one of the at least one measured pressure signature deviates from the at least one reference pressure signature by more than a tolerable margin.
