An arrangement for shaft sealing and to a method for monitoring the sealing of the shaft seal are provided. The arrangement includes a rotating slide ring and a stationary slide ring, with a sealing gap having a lubricating film therebetween. The arrangement includes at least one sound transducer for generating and/or receiving exciting sound waves in the form of Lamb Rayleigh waves in at least one slide ring. The signals of the sound transducer are evaluated by an evaluation unit to determine the condition of the lubricating film in the gap.

Monitoring slide ring seal

An optoelectronic sensor includes at least one light transmitter for the transmission of light signals into a monitored zone and at least one light receiver for the reception of transmitted light signals. In this respect, the received light signals are converted into electrical received signals in the light receiver. The light signals transmitted by the light transmitter are each generated on the basis of an output signal spread in accordance with a frequency spreading technique (spread spectrum) and provided with an offset applied for the generation of a unipolar signal. The electrical received signals can be supplied to a high-pass filter in the light receiver. Means for interference suppression are provided to automatically measure repeatedly or continuously respective then current interference; to analyze it in the time domain and/or in the frequency domain; and to compensate it at least substantially in dependence on the respective result of the interference analyses.
