Zusammenfassung:	A system for detecting the presence of water in oil, comprises an array of infra-red emitters for emitting light at a first plurality of wavelengths and an array of infra-red receivers, each arranged to detect light from a respective emitter at the respective wavelength and produce a light signal representative of the light detected. The receivers are spaced from the emitters by a gap through which oil in use may pass. A processor is provided to analyse and compare the respective light signals to determine an amount of water present in the oil. By observing variations in absorption, the presence of water can be identified.
