Product Description:
The KSJB3 series quartz flexible accelerometer is a small yet
highly precise military-grade sensor designed for a variety of
inertial navigation applications. It stands out for its exceptional
long-term stability, repeatability, starting performance,
adaptability to different environments, and high reliability. This
adaptable sensor can be employed for static and dynamic testing and
serves as both a standard vibration and inclination sensor. Its
output current exhibits a linear relationship with the applied
force or acceleration, offering users the flexibility to fine-tune
output precision by selecting the appropriate sampling resistance.
Furthermore, the built-in temperature sensor allows users to
compensate for offset values and scale factors, mitigating the
influence of ambient temperature variations. Its applications
encompass inertial measurements in military inertial navigation
systems and vibration isolation and inclination testing of
precision instruments and equipment in aerospace, aviation, naval,
and defense sectors.
