small accelerometer wide range quartz accelerometer for inertial navigation dynamic test vibration sensor
JB3 series quartz flexible accelerometer is a miniaturized, high-precision, large-range military inertial navigation grade accelerometer product with excellent long-term stability, repeatability, startup performance, environmental adaptability and high reliability. It can be used for both static and dynamic testing and is also a standard vibration sensor.
The product adopts a unique miniaturized design and packaging process, and the output current has a linear relationship with the force or acceleration received. Users can select an appropriate sampling resistor through calculation to achieve high-precision output. A temperature sensor can be built-in according to user needs, which can be used to compensate the offset value and scale factor to reduce the influence of ambient temperature.
Application areas: inertial measurement of military inertial navigation systems in aerospace, aviation, ships, weapons and other fields and vibration isolation testing of precision instruments and equipment.
