Quartz flexible accelerometer
KT-JB3 series quartz flexible accelerometer is a miniaturized, high-precision inertial navigation class accelerometer for a large number of military applications. The product has excellent long-term stability, repeatability, start-up performance, environmental adaptability and high reliability, which can be used for static and dynamic testing. It is also a standard vibration sensor and inclination sensor.
The product adopts a unique miniaturized design and packaging process, the output current and the force or acceleration is linear relationship, users can calculate and select the appropriate sampling resistance, to achieve high precision output. And according to user needs built-in temperature sensor, used to offset value and scale factor compensation, reduce the impact of environmental temperature.
Applications: inertial measurement of military inertial navigation system in aerospace, aviation, ships, weapons and other fields and precision instrument equipment vibration isolation test and inclination test.
