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.
