We are concerned about water & metal in the oil and not about comprehensive analysis. When wear is occuring particle counters can show a trend often before the vibration has changed. When the vibration changes, it indicates the source of the wear debris as a gear set or bearing. Our choice is the inductive type, with a coil around a 4 mm dia ceramic cylinder, through which the oil flows, because they detect significant damage debris, and it is difficult to block them. They are sensitive to Fe particles in 5 size ranges from 50 to 800+ um and non Fe particles in 5 size ranges from 150 to 1600+ um, which covers minor to major wear trending. Rolling mill scale though Fe based is not conductive, and not detected, thus avoiding false data. Inductive Wear Debris Sensor Water causes oil to loose it’s lubricating ability even at low levels of relative humidity, and so reduces machine life span to a small fraction of normal. So especially if there is an oil / water heat exchanger, knowing relative humidity, RH, continuously is very useful. This sensor reads 0 to 100% RH and temperature to 100 deg C which is appropriate for normal industrial gearboxes. Catching a leak early prevents needless wear. for detail visit
