inertial measurement accelerometer , high-precision vibration quartz sensor , inertial navigation system accelerometer
Features
The output current of the product has a linear relationship with the force or acceleration received, and the user 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 fields: inertial measurement of military high-precision inertial navigation systems in aerospace, aviation, ships, weapons and other fields and vibration isolation testing of precision instruments and equipment.
JB2 series quartz flexible accelerometer is a high-precision, large-range (up to 100g) military inertial navigation grade accelerometer product with excellent long-term stability, repeatability, startup performance, environmental adaptability and high reliability. It can be used for static testing as well as dynamic testing, and it is also a standard vibration sensor.
