Method for monitoring an oil and gas lubricating device with the aid of a striae sensor

摘要

A method is disclosed for monitoring an oil and gas lubricating device, with which an oil film, while forming striae, can be conveyed by an airflow along a wall of a supply line to a lubrication point, in which the temporal change in the striae is detected by a striae sensor, and a striae signal that is representative of the temporal change in the striae is generated. In order to further develop known methods for monitoring an oil and gas lubricating device, thereby preventing faults during the evaluation of the striae signal, the striae signal is smoothened by calculating an average value of the striae signal over a predetermined averaging interval.
