The other thing to consider is the mass of the sensor, the

The "flexible coupling" provided by the epoxies I've tried is
causing issues.

It's been suggested that I try silver-filled epoxy and potting
compound.
Dental cement was also a suggestion. I'm looking at all of these.

Devcon Plastic Welder or Stabilit Express are methacrylates that are
much harder and stronger than the hardware store epoxies and cheap
enough to try.
