Oil has the ability to hold a certain amount of dissolved water. The maximum amount of water that oil can hold is characterized by the "saturation point". Above this point free water precipitates, which can lead to corrosion inside an aggregate.
Leaving behind basic measuring technology of free water in oil or emulsion, our system senses the absolute content of absorbed water in oil.
The Water in Oil Sensor FRG00035 physically detects the ‘water activity’ characterized by value AW.
