The ACC141 Series are linear accelerometers
that produce a high level output proportional to the
instantaneous acceleration from static to 3000 Hz
(depending upon range). The excellent dynamic response
is enabled by using air damping which has much better
temperature properties than fluid damping. The rugged
capacitive sensor allows the high overload properties
and delivers excellent accuracy and long term stability.
The rugged stainless steel case with O-ring seal provides
excellent environmental protection and the integral base
plate make installation and mounting quick and isolates
the unit from mounting strain.
