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.
