So for this customer gig I need to measure the actual acceleration of a
parallel-rod transmission line that's being pounded into the ground with
a built-in slide hammer. (It's for measuring soil moisture and salinity
by TDR.)

We're thinking about putting the TDR pulser and sampler in the part that
gets pounded (in a potted module obviously), so knowing how bad the
acceleration gets is going to be important. I expect that it'll be
several hundred g in volcanic soil, so a full-scale range of 1000-2000 g
would be about right.

None of the MEMS IC accelerometers go anywhere near that high.
Measurement Specialties makes them, but they're $160 in onesies, e.g.

Ceramic resonator maybe?
