Abstract
A dynamic pressure probe for a combustor comprising a holder body having a pressure sensing passage; a pressure sensor and a pressure chamber located in a housing portion arranged substantially perpendicularly to the pressure sensing passage; and wherein the pressure chamber communicates with the pressure sensing passage via a relatively small aperture in a wall separating the pressure chamber from the pressure sensing passage.
Claims23
A dynamic pressure probe for a combustor comprising a holder body having a pressure sensing passage;
- a pressure sensor and a pressure chamber located in a housing portion arranged substantially perpendicularly to said pressure sensing passage;
- and wherein said pressure chamber communicates with said pressure sensing passage via a relatively small aperture in a wall separating said pressure chamber from said pressure sensing passage.
A dynamic pressure probe comprising a holder body having a first passage therein adapted to receive a pressure signal, a pressure sensor including at least a pressure sensing portion located within a sleeve seated within a pressure sensor housing portion, said sleeve engaged with a wall of said housing portion;
- said pressure sensor including a diaphragm having one face exposed to a pressure chamber within said sleeve between said pressure sensor and said wall;
- and wherein an aperture in said wall of said housing connects said pressure chamber to said first passage.
A method of obtaining a dynamic pressure signal from a combustor comprising:
- a) supplying a dynamic pressure signal from the combustor through a first passage, said first passage exposed to a mutually perpendicularly arranged sensor diaphragm remote from said combustor;
- b) transmitting said pressure signal beyond said sensor diaphragm to a signal damping mechanism;
- and
- c) supplying compressor discharge air to said signal damping mechanism to remove any condensation therein.
