Technical
Description
This
high-performance
accelerometer
features
a
unique
miniaturized
design
with
advanced
high-temperature
and
seismic
resistance
capabilities.
Utilizing
specialized
packaging
technology
and
custom
circuitry,
it
delivers
flow
proportional
to
input
acceleration.
Users
can
select
appropriate
sampling
resistors
to
achieve
high-precision
output.
Optional
built-in
temperature
sensors
enable
compensation
for
offset
values
and
scale
factors,
reducing
environmental
temperature
effects.
Ideal
for
oil
drilling
inclination
measurement
and
precision
instrument
vibration
isolation
testing.
