Abstract:
A system includes a tubular member (60) including a radially outer surface (60c) and a sensor assembly (128). The sensor assembly includes a strain sensor coupled to the radially outer surface. In addition, the sensor assembly includes a first coating having (134) a first hardness and a first tensile strength. The first coating encases the strain sensor (131,130) and at least part (64) of the outer surface. Further, the sensor assembly includes a second coating (136) having a second hardness that is greater than the first hardness and a second tensile strength that is greater than the first tensile strength. The second coating encases the first coating and at least another part (68) of the radially outer surface.
