Static And Dynamic Accelerometer Current Output Acceleration Meter Analog Output Acceleration Transducer
Description
JB3 accelerometer family utilizes unique quartz flexible sensors. The small accelerometer is designed for measurement of Inertial accelerations in aerospace environment,It is the predominant sensor used in china’s commercial and military aircraft strap-down inertial navigation systems.The long-term Repeatability and superior reliability characteristics of the JB3 make it the best value inertial-grade accelerometer available on the market today.
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.
Features
1. Excellent turn-on repeatability performance
2. Environmentally rugged
3. Analog output
4. Field adjustable range
5. Smaller outline size(￡30gram)
