⻬ High EMI Noise Rejection
The ACC102A accelerometer uses
a shear mode design for high
performance. It has a rugged,
stainless steel inner structure
covered by a molded polymer. This
construction makes the ACC102
impervious to harsh environments,
such as alkaline coolants, hot oil,
and water sprays, resulting in long,
reliable service. Additional features
include high shock protection (to
protect from dropping or mishandling),
cross wire protection (protects
against miswiring), and up to
1000-volt static discharge protection.
The ACC102 has a high 100 mV/g
output and measures across wide
frequency and acceleration ranges.
A low-impedance cable allows for
runs up to 1000'. The ACC102
exhibits the low-noise floor and
high-amplitude linearity one would
expect in more expensive units.
