Abstract
A component adapted to transmit a dynamic pressure signal from a high temperature environment to a location where it can be measured without causing significant attenuation of the signal. In particular, the component provides for a dynamic pressure signal transmission in the manner that will not result in the formation of condensation in the measurement system and thus eliminates the need to periodically purge condensate from the system.
Claims24
A dynamic pressure probe holder for a combustor comprising:
- a holder body having a pressure sensing passage and housing a pressure sensor operatively coupled to said pressure sensing passage;
- and
- an elongated acoustic damping coil coupled to so as to be in flow communication with said pressure sensing passage, said damping coil being disposed in heat exchange relation to a heat source so as to substantially avoid condensation formation in said coil.
A dynamic pressure probe holder for a combustor comprising:
- a holder body having a pressure sensing passage and defining a pressure sensor chamber operatively coupled to said pressure sensing passage;
- and
- an elongated acoustic damping coil having a bore operatively coupled to said pressure sensing passage, said damping coil being wound about said holder body so as to be disposed in heat exchange relation thereto so as to substantially avoid condensation formation in said coil.
A method of obtaining a dynamic pressure signal from a combustor while preventing the formation of condensation, comprising:
- providing a dynamic pressure probe device comprising:
- a holder body having a pressure sensing passage and housing a pressure sensor operatively coupled to said pressure sensing passage;
- and an elongated damping coil coupled to said pressure sensing passage, said damping coil being disposed in heat exchange relation to a heat source;
- supplying a dynamic pressure signal from the combustor through said pressure sensing passage;
- detecting said dynamic pressure signal with said pressure sensor;
- and
- transmitting said pressure signal downstream from said pressure sensor to an acoustic damping system comprising said coil;
- whereby heat from said heat source prevents the formation of condensation in said coil.
