Abstract: The disclosure relates to a mechanical seal for sealing at least one fluid-carrying channel and/or space extending in a stationary component and/or a rotating component from the environment, having a seal ring which is supported in a sealing manner in the axial direction against a mating ring and, to compensate for wear on its end sealing surface or on a mating face, is supported against the mating ring elastically and movably in the axial direction with this sealing surface; having a housing which movably accommodates the mechanical seal ring in the axial direction and encloses the mechanical seal ring with a circumferential part in the circumferential direction.

Abstract: The disclosure relates to a mechanical seal for sealing a fluid-conducting channel and/or space extending in a stationary component and/or a rotating component from the environment, having a slide ring which is supported in the axial direction against a counter ring in a sealing manner and, to compensate for wear on its front-end seal face or on a counter face, is supported against the counter ring elastically and movably in the axial direction with this seal face; having a position sensor to detect the position of the slide ring in the axial direction. The disclosure is characterized in that a temperature sensor is provided on a leakage side of the seal face facing away from the channel and/or space, which sensor at least indirectly detects a temperature which is dependent on the magnitude of a leakage flow passing from the channel and/or space via the seal face.

Abstract: The disclosure relates to a method for measuring the size of a leakage flow of a seal. In exemplifications of the disclosure, a leakage sensor is provided on a leakage side of the seal, said leakage sensor comprising at least one heating element and at least two temperature sensors which are in heat-transferring connection with the leakage flow.
