A method of monitoring the wear of the sealing faces of a mechanical face seal comprising; positioning a probe radially of the axially moveable seal face member of the seal or a component which moves axially with the seal face member; producing a signal which is directed radially outwardly from the surface of the seal face member or component so that it may be picked up by the probe; and arranging the surface of the seal face member or component such that there is a change in signal, indicative of the wear on the sealing faces, as the seal face member moves axially with respect to the probe.
