The SG-2 series quartz flexible accelerometer is a high-precision, wide-range military inertial navigation-grade accelerometer (with a range up to 100g). It features excellent long-term stability, repeatability, start-up performance, environmental adaptability, and high reliability. It can be used for both static testing and dynamic testing, and also serves as a standard vibration sensor and tilt sensor.

The output current of the product has a linear relationship with the applied force or acceleration. Users can select an appropriate sampling resistor through calculation to achieve high-precision output. Additionally, a built-in temperature sensor can be provided according to user requirements, which is used for compensating the bias and scale factor to reduce the impact of ambient temperature.

Inertial measurement of military high-precision inertial navigation systems, as well as vibration isolation testing and inclination testing of precision instruments and equipment in aerospace, aviation, shipbuilding, ordnance and other fields.
