a system and method disclosed may include a dynamic pressure sensor or probe having a wave guide and wave guide tube and a temperature sensor disposed therethrough in order to optimally install and position the temperature sensor to measure combustor flame characteristics . the dynamic pressure sensor is preferably positioned or mounted on the outer casing of the combustor . by taking advantage of the placement of an existing dynamic pressure sensor , a temperature sensor — for instance a fine wire temperature probe — can be disposed through the interior of the dynamic pressure sensor so that combustion flame characteristics can be measured near the combustion liner .
