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.
