JDB-KT-JB2 series quartz flexure accelerometer is a high-precision, large-range inertial accelerometer (up to 100g), the product has excellent long-term stability, repeatability, start-up performance, environmental adaptability and high reliability, etc. It can be used for both static and dynamic testing, and is also a standard vibration sensor and inclination sensor.
The output current of the product is linearly related to the force or acceleration, and the user can select the appropriate sampling resistance through calculation to achieve high-precision output. And according to the user's needs, the built-in temperature sensor can be used to compensate the bias value and scale factor to reduce the influence of ambient temperature.
Applications: Inertial measurement of high-precision inertial guidance system in aerospace, aviation, marine and other fields, and vibration isolation test and inclination test of precision instruments and equipments.
