US 5,612,497 A · Adaptor for monitoring a pressure sensor to a gas turbine housing

Abstract

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

Dependent claims

The combination of an adaptor and pressure sensor for attachment to the exterior side of a wall to measure pressure variations in a space interior to the wall, said combination comprising:

(a) as the adaptor, a carrier means having a hollow middle portion, and oppositely disposed first and second end portions;
(b) means in the first end portion for mounting the carrier means in a hole defined in the wall so that the hollow middle portion and second end portion extend in a direction outwardly and away from the exterior surface of the wall;
(c) a pressure sensor affixed to the carrier means remote from said first end portion and separated therefrom by the hollow middle portion of the carrier means, whereby the pressure sensor is remotely positioned from the wall on the exterior side thereof;
(d) an opening defined in the first end portion which provides communication with the space interior to the wall;
(e) the carrier means defining a generally sealed, internal space communicating between the opening in the first end portion and the remotely positioned pressure sensor;
(f) said generally sealed internal space being defined in part by the bore of an elongated tube means, said tube means being in communication with the opening in the first end portion and extending through the hollow middle portion of the carrier means, whereby pressure variations in the space interior to the wall are communicated to the remotely positioned pressure sensor through the bore of the tube means.
