Abstract:
A gas-sensing probe adapted for in situ use in a combustor, comprising:a support member having a proximal end and a distal end, the support member being elongated in a direction extending between the proximal and distal ends; a housing disposed at the distal end of the support member; a gas sensor rigidly supported within the housing such that the gas sensor does not move with respect to the housing when a length of the support member changes due to temperature changes thereof, the gas sensor being configured and arranged so as to be in fluid communication with an environment external to the housing when in use in the combustor; and sensor wires extending between the gas sensor and the proximal end of the support member, the sensor wires being configured and arranged such that the sensor wires are not caused to break by elongation of the support member due to thermal expansion and resulting movement of the gas sensor away from the proximal end of the support member because of the gas sensor being rigidly supported within the housing.
