1. 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.
