Abstract
A probe gas analysis system is provided. The probe gas analysis system comprises a probe body configured to be exposed to a source of process gas. The probe gas analysis system also comprises a sensor cell assembly having a sensor cell with a sensing side and a reference side. The sensing side is disposed to contact the source of process gas, and to generate a signal indicative of a detected difference in oxygen concentration between the reference side and the sensing side. The probe gas analysis system also comprises a substantially permanent seal coupling the sensor cell assembly to the probe body, wherein the substantially permanent seal separates the reference side from the sensing side.
