ABSTRACT:
An on-line gas-in-oil monitoring apparatus and method extracts certain reducing or combustible gases from oil and detects their presence and concentration substantially simultaneously using a sensor. The sensors are sintered metal oxide semi-conductors with adsorbed oxygen. The presence of a reducing or combustible gas proportionally increases the conductivity of the semi-conductor. Any resultant change in conductivity indicates the presence and concentraton of the reducing or combustible gas in the semi-conductor. After the analytical cycle the sensors are regenerated by exposure to oxygen.
