Abstract
It is very challenging to measure moisture levels in oils. There is not a good method to measure it. Using the novel moisture sensor, we tried various methods to measure the moisture levels in oils. The initial trials are to immerse the sensor chip into the oils to see any sensor reading changes with the change of moisture levels in oils. It was observed that the sensor reading was unstable. The idea for immersion of the sensor chip into the oils failed. The last idea is to heat the oil to let all moisture evaporate fully. Before heating, the dew point (PPMv) can be measured. During heating the dew point (PPMv) increased to the maximum and began to decrease until the dew point (PPMv) became the same as dew point (PPMv) before heating. All moisture inside the oil was fully evaporated. By integration of the dew point (PPMv) with time or the area inside the curve (S), one can link S with moisture levels using an empirical parameter A. Once A is determined, one can obtain S in any oils to calculate the moisture levels in the Oil.
