Abstract
A wall structure is provided for mounting an oxygen sensor probe to accurately measure the oxygen content of flowing elevated temperature atmosphere confined on one side of the wall. The sensor probe is protectively positioned and cushioned within a probe accepting bore through the wall by a flexible fibrous refractory material which thermally insulates and seals the probe within the bore from the surrounding environment. The sensing tip of the probe extends through the wall structure and is exposed to the elevated temperature combustion gases.
