KSJB3 series quartz flexible accelerometer is a small, high precision, a large number of military inertial navigation level accelerometer, the product has excellent long-term stability, repeatability, starting performance, environmental adaptability and high reliability and other characteristics, can be used for static testing can be used for dynamic testing, is also a standard vibration sensor and inclination sensor.
The product adopts a unique miniaturized design and packaging process, the output current and the force or acceleration are linear, the user can choose the appropriate sampling resistance by calculation, to achieve high precision output. The built-in temperature sensor can be used to compensate the offset value and scale factor to reduce the impact of ambient temperature according to user needs.
Applications: Inertial measurement of military inertial navigation system and vibration isolation test and inclination test of precision instruments and equipment in aerospace, aviation, ships, weapons and other fields.
