KSJB2 series quartz flexible accelerometer is a high-precision, inertial navigation level accelerometer for a large number of military applications (up to 100g), the product has excellent long-term stability, repeatability, start-up performance, environmental adaptability and high reliability characteristics, can be used for static testing can be used for dynamic testing, is also a standard vibration sensor and inclination sensor.
The output current of the product is linearly related to the force or acceleration received, and the user can select the appropriate sampling resistance through 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: Quartz flexible pendulum accelerometers have been widely used in the measurement of various linear accelerations and vibration accelerations and the measurement of parameters such as speed, distance, angular velocity, and angular displacement. Successfully used in satellite microgravity measurement systems, high-precision inertial navigation systems, rock, and soil-based borehole surveys and oil drilling, continuous inclinometer systems, launch vehicles, ballistic missiles, spacecraft, and other military and civilian fields.
