Abstract
An oxygen sensor constructed as a coulometric sensor and capable of detecting oxygen concentrations in the range of 1% or greater concentrations. The coulometric sensor utilizes a gas flow path which has a predetermined section constructed with oxygen-permeable tubing, wherein a portion of the oxygen flowing through the gas flow path will permeate into the sensor to generate an electric current flow indicative of the permeating oxygen level. The length of the tubing section which is constructed from oxygen-permeable material maybe selectively adjusted to control the relative attenuation of oxygen flow through the sensor.
