High-Precision Military Inertial Navigation Grade Accelerometer
KSJB1 series quartz flexible accelerometer is a high-precision military inertial navigation grade accelerometer. The product has excellent long-term stability, repeatability, starting performance, environmental adaptability and high reliability. It can be used for static test and dynamic test, and is also 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.
