A system and method for monitoring a dry gas seal positionable between a stationary housing and a rotatable shaft. A plurality of sense elements may rotate in response to the rotation of the rotatable shaft and a speed sensor may sense the speed of the rotatable shaft at speeds below one thousand rotations per minute based on sensing the plurality of sense elements. An acoustic emissions sensor may sense when a first seal face and a second seal face forming a seal interface of the dry gas seal are in an operational condition relative to one another. A processor may receive output signals from the speed sensor and the acoustic emissions sensor, and may establish an operating condition of the dry gas seal based on the signal from the speed sensor when the first seal face and the second seal face reach the operational condition relative to one another.

A real-time monitoring and analysis method for a mechanical seal. In the method, an acoustic emission signal generated by a friction pair at a mechanical seal end surface is measured; a specific acoustic source generate signals on a plurality of specific frequency bands on an acoustic scale. In a seal operating process motion causes the acoustic emission signal to change on a dynamic time scale equivalent to a period of rotation. In a long-term seal service process, cumulative performance changes occur on a service time scale due to running-in, wear, and/or aging of elastic elements; for this feature, the long-term change process of the acoustic emission signal needs to be considered. Analysis is performed, on multiple scales, in combination with auxiliary information and with determined physical characterization quantities passed to scales of longer time, thereby determining the real-time working state of the seal and providing a performance change expectation of the seal. In an embodiment, the acoustic scale transfers frictional power consumption, maximum contact depth and leakage rate to the dynamic scale, and the dynamic scale transfers a wear rate to the service scale, while part of the auxiliary information of the acoustic scale analysis may come from the results of the service scale analysis.
