Data Logging Accelerometers

We had a project in full-active suspension on off-road vehicles some y ago.
www-page; "http://www.luth.se/depts/mt/ene/articles/rigg/A_cab.html"
There where a set of transducers developed for this application as
accelerometers 0-100Hz, potentiometers and inclinometers.
All units had mil-std, 4-20 mA and fault detection.

An est. prize for this single axis accelerometer would be .LE. $400 in low
quantity.
