摘要 |
The invention refers to a mechanical seal, comprising at least one pair of interacting seal rings (3, 4), one of which is provided for a common rotation with a rotating component (2), and the other of which is retained at a stationary component (20) in a torque-proof manner against a rotation with the rotating component (2), and a monitoring device (6) for monitoring an operating state of the mechanical seal. The invention stands out in that the monitoring device (6) comprises a beam (7) including a sensor element for detecting a bending of the beam, in particular a strain gauge, wherein the beam (7) is arranged in a recess (14) in the stationary seal ring (4) and the beam (7) contacts a wall (14a) of the recess (14) in the stationary seal ring with a predetermined pretension, and further comprises an adjusting device in order to adjust a position of the beam (7) with respect to the recess (14).
