Technical
Description
The
JB4
series
accelerometer
features
high
temperature
resistance
and
shock
resistance.
Utilizing
unique
design
and
advanced
packaging
technology,
it
delivers
superior
performance
in
demanding
environments
with
excellent
reliability.
The
device
incorporates
a
dedicated
circuit
that
provides
output
proportional
to
acceleration
input,
enabling
measurement
of
both
static
and
dynamic
acceleration.
Users
can
select
appropriate
sampling
resistors
for
optimal
accuracy
output.
The
built-in
temperature
sensor
allows
compensation
for
deviation
value
and
scale
factor,
minimizing
temperature
effects.
