Overview
The
ACC1
series
quartz
flexible
accelerometer
is
a
high-precision
vibration
sensor
with
exceptional
long-term
stability,
repeatability,
start-up
performance,
and
environmental
adaptability.
Designed
for
both
static
and
dynamic
testing
applications,
it
serves
as
a
reliable
standard
for
vibration
and
tilt
measurement.
The
sensor's
output
current
maintains
a
linear
relationship
with
applied
force
or
acceleration.
Users
can
select
appropriate
sampling
resistance
to
achieve
high-precision
output.
An
optional
built-in
temperature
sensor
enables
compensation
for
bias
and
scale
factor
variations,
reducing
environmental
temperature
effects.
