Product Description

Quartz-Flexure Seismic Accelerometer Amorphous Quartz Vibration Meter Dynamic Accelerometer For Inertial Navigation
 
Description
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)
