| 摘要 |
The invention relates to an adaptor (10) for mounting a pressure sensor (12) for a high temperature system comprising a sensor carrier means (40) with an axis (26) of elongation, said carrier means (40) being provided at one axial end thereof with mounting means for sealingly mounting said carrier means (40) in a hole (14) in a wall (16), with an end face (36) of said carrier means (40) within a borescope hole (14) being provided with an opening for entrance of pressure fluid from the interior (20) of a gas turbine wall (16) into said carrier means (40) further being provided at the other axial end thereof with a recess (30) for sealingly receiving the pressure sensor (12). The adaptor (10) further comprises a tube means (42) extending through said carrier means (40) parallel to said axis (26) of elongation with one end of said tube means (16) being in fluid connection with said recess (30) and the other end of said tube means (16) being in fluid connection with said opening, said tube means (16) thus forming at least a part of a fluid channel (10) said fluid channel (48) connecting said recess (30) with said opening. The adaptor (10) provides for cooling of the pressure sensor and enables the measurement of high frequency variations.
