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. A processor may receive output signals from the speed sensor and may establish a position of the dry gas seal or an operating condition of the dry gas seal based on the signal from the speed sensor.
