There is one very interesting case to do the condition monitoring of conveyor pully bearings. These big conveyor pullys are used in steel, cement plants etc and are having very high down time costs if bearings of these pullys go bad. The challange is that the rpm of thesecpullies is very low 10 to 15 rpm! bearing frequency of vibrations on these pullies is 5 to 10 hz and amplitude of vibrations is very low 1 to 2 mG ! So needs very special vibration sensors to monitor these!
