A system and method for monitoring a dry gas seal positionable between a stationary housing (18) and a rotatable shaft (29). A plurality of sense elements (44) may rotate in response to the rotation of the rotatable shaft (20) and a speed sensor (17) may sense the speed of the rotatable shaft at speeds below one thousand rotations per minute based on sensing the plurality of sense elements (44). An acoustic emissions sensor (19) 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 (11) may receive output signals from the speed sensor (17) and the acoustic emissions sensor (19), 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. 一种用于监测可定位在固定壳体（18）和可旋转轴（29）之间的干气密封件的系统和方法。多个敏感元件（44）可响应于可旋转轴的旋转而旋转，并且速度传感器（17）可基于感测所述多个敏感元件（44）在低于一千转每分的速度下感测可旋转
