High-Precision Military Inertial Navigation Grade Accelerometer
The KSJB1 series quartz flexible accelerometer sensor is a
high-precision military inertial navigation grade accelerometer
sensor, known for its exceptional long-term stability,
repeatability, starting performance, adaptability to different
environmental conditions, and overall high reliability. It serves
dual purposes, effectively handling static and dynamic tests, and
functions as both a standard vibration sensor and inclination
sensor.
The output current of the product is linear with the force or
acceleration, and the user can select the appropriate sampling
resistance through calculation to achieve high-precision output.
And can be built in temperature sensor according to user
requirements, used for the compensation of partial value and scale
factor, reduce the impact of environmental temperature.
Application: Inertial measurement and vibration isolation test of
high-precision inertial navigation system in aerospace, aviation,
ship, weapon and other fields.
