Description
KT-JB2 series quartz flexible accelerometer is a high-precision inertial navigation level accelerometer for a large number of military applications (up to 100g). The product has excellent long-term stability, repeatability, start-up performance, environmental adaptability and high reliability, which can be used for static test or dynamic test. It is also a standard vibration sensor and inclination sensor.
The output current of the product has a linear relationship with the force or acceleration received. Users can select the appropriate sampling resistance through calculation 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.Quartz Flexible Accelerometer for aerospace
Applications: inertial measurement of military high-precision inertial navigation system in aerospace, aviation, ships, weapons and other fields and precision instrument equipment vibration isolation test and inclination test.
Features
1. Excellent turn-on repeatability performance
2. Environmentally rugged
3. Analog output
4. Field adjustable range
5. Internal temperature sensor for thermal compensation（option）
6. High range(100g)
Configuration Drawing and interface
