A transducer sensor is positioned within a hollow of the body of a housing. The housing has an extending alignment pin, which pin coacts with a corresponding slot or aperture in the wall of a vessel whose pressure or temperature is to be monitored. The transducer body is associated with a connector where the alignment pin is placed and extends from the housing in a fixed relation to the connector. A suitable aperture or slot in the wall of the vessel to be monitored accommodates the extending pin whereby when the transducer is placed in the vessel aperture the connector associated with the transducer is always located in proper position. Positioned on the housing is a sliding nut which can move in a direction parallel to the central axis of the housing and either to the right or left. This sliding nut is rotatably positioned in the housing and coacts with threads formed in the aperture in the wall of the vessel to enable tightening of the transducer housing when placed in the wall and when the alignment pin is positioned within the corresponding slot or aperture. This assures a proper alignment so that an external connector which is not moveable or rotatable can be immediately connected to the transducer connector without further experimentation or adjustment.
