KT-JB1 QUARTZ FLEXIBLE ACCELEROMETER
Quartz flexible accelerometer series is a high-precision inertial navigation class 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 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.
Applications: inertial measurement of high-precision inertial navigation system and vibration isolation test of precision instruments and equipment in ships and other fields.
Features
1. Excellent turn-on repeatability performance
2. Environmentally rugged
3. Analog output
4. Field adjustable range
5. Three fastener precision mounting flange
6. Internal temperature sensor for thermal compensation（option）
7. For the scale factor we can adjust for you.
Configuration Drawing and interface
