Method for condition monitoring of apparatuses

摘要

A method of monitoring the condition of apparatuses wherein the condition of the apparatus is measured from one or more rotating objects by means of a fixedly mounted condition monitoring system during the operation of the apparatus when it operates at its normal operating speed. In the method, at least one signal indicating the condition of the apparatus and the steadiness of the operation is measured during the change in the operating speed of the apparatus and desired characteristic values and/or functions are calculated from each signal measured in this manner as a function of measured time and/or rotational speed.
