Welcome to KaiTuo Precise Instrument Co., Ltd
As the inertial navigation standard by which others are measured, KT produces the JB3. It is the smaller outline accelerometer.
JB3 features a patented Q-flex& etched-quartz-flexure seismic system. An amorphous quartz proof-mass structure provides excellent bias, scale factor, and axis alignment repeatability.
The integral electronics develops an acceleration-proportional output current providing both static and dynamic acceleration measurement. By use of customer supplied output load resistor, appropriately scaled for the acceleration range of the application, the output current can be converted into a voltage.
The JB3 also includes a current-output.
Features
1. Excellent turn-on repeatability performance
2. Environmentally rugged
3. Analog output
4. Field adjustable range
5. Smaller outline size
