Double-C Seismic Accelerometers not detecting centripetal/centrifugal force

Is there a reason why this doesn't happen anymore? I remember using spinning stuff in orbit and measuring the G-force using those. That feature was gone in the last two versions.

I have no idea

Wait, what? I didn't know that happened. Perhaps it's a bug. I'll make sure to let the QA team know.

Putting the Double-C on a vessel and rotating the same vessel never produced any measurements as far as I recall. That's because the Double-C displays the forces as if it was placed perfectly on the center of mass, regardless of its actual position (and being an accelerometer, it's only able to measure directional forces - you'd need a gyroscope to measure rotational forces).

Putting the seismometer on a vessel that is inside a second vessel, which is rotating (inducing centrifugal force on the first vessel) does measure acceleration correctly, nothing broken there (and I think this is what you remember).

I put up a quick test rig to demonstrate:

I don't think it broke in 0.25, I think it was never implemented correctly, as far as single vessel use is concerned.

It used to work. I remember it working on one centrifuge station I've built. I was getting a bit over 1 G with moderate rotation. However in the last two, possibly three versions of KSP, such feature is gone. But it did exist.

I think it'd be really cool if KSP used the local acceleration (not just gravity) field to orient kerbals on EVA. This would allow for things like what the OP is suggesting (centrigual force readings) as well as letting kerbals on EVA walk inside spinning rings. That'd be cool!
