Abstract
An oxygen number density or concentration sensor including a sampling luminescent oxygen probe located in a fluid environment, and a gas impermeable enclosure located in the fluid environment and a reference luminescent oxygen probe located within the gas impermeable enclosure, wherein the sampling and reference luminescent oxygen probes are formed by an ideal PSP. A predetermined fixed oxygen number density or concentration is provided within a medium contained in the gas impermeable enclosure. A detector receives signals corresponding to luminescent emissions of the sampling and reference probes. A processor determines a number density or concentration of oxygen in the fluid environment from a signal generated at the sampling probe with reference to an oxygen number density or concentration dependent signal generated at the reference probe.
