A sensor body has a gap in which a sample of the oil may be received and a reflecting surface, the second end of the optical fibre being embedded in the sensor body and having an end face spaced from the reflecting surface across the gap. Light emitted from the optical fibre can pass through the sample of oil and be reflected by the reflecting surface back into the optical fibre. By interferometry of the respective signals, the condition of the oil can be determined.

Abstract: The present invention provides a dynamic seal for enclosing a radial gap between coaxial, relatively rotatable inner and outer members. The dynamic seal includes an inner seal part, mountable to the inner member; an outer seal part, mountable to the outer member; and a counterface part radially suspended between the inner and outer seal parts and coaxial therewith. Each of the inner and outer seal parts provides a set of first and second sealing elements, which bear against oppositely oriented axial surfaces of the counterface part. The counterface part is thus axially retained in both directions by the inner seal part at a radially inner contact location, and is axially retained in both directions by the outer seal part at a radially outer contact location.

The second rotatable member is coupled with the first rotatable member such that the second angle is equal to the first angle times the ratio of the first radius and the second radius. The first radius is equal to a first integer times a factor, while the second radius is equal to a second integer times said factor. The product of the first number and the second integer, and the product of the second number and the first integer, are co-prime.
