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.
