The JDB-JB1 series quartz flexible accelerometer is a high-precision inertial grade accelerometer with excellent long-term stability, repeatability, start-up performance, environmental adaptability, and high reliability. It can be used for both static and dynamic testing, and is also a standard vibration sensor and tilt sensor.
The output current of the product is linearly related to the force or acceleration it receives. Users can select the appropriate sampling resistor through calculation to achieve high-precision output. And it can be equipped with a built-in temperature sensor according to user needs for compensating for bias and scaling factors, reducing the impact of environmental temperature.
Application areas: Inertial measurement of high-precision inertial navigation systems and vibration isolation testing of precision instruments and equipment in aerospace, aviation, shipbuilding, weapons and other fields
