1. A subsea sensor module, comprising:
a sensor housing having a first section that defines a first outer profile, a transition section that defines a transition outer profile, and a ridge portion;
a module flange having an inner profile that is the same as the transition outer profile, a planar bolt surface, and a bottom surface parallel to and opposite the planar bolt surface;
a housing shoulder formed as part of the transition outer profile, the housing shoulder defining a first contact face that is not perpendicular to the bolt surface;
a flange shoulder formed as part of the inner profile, the flange shoulder defining a second contact face that is parallel to the first contact face; and
wherein the module flange is shrink fit mounted to the sensor housing such that the first contact face and the second contact face contact one another and the ridge portion extends axially beyond the bottom surface of the module flange.
