JA-40GA Accelerometer

Key features

Applications•••••••••

Ultra-low noise
Excellent thermal stability
Low frequency operation-20 °C to +70 °C operating temperature
Easy to install

The JA-40GA is a high performance servo balanced
quartz accelerometer which has been developed formeasuring very low levels of vibration. The signal
processing circuit has been optimized to provide very
low output noise while maintaining excellent Scale factor
and Bias stability over the whole operating temperature
range.

Structural health monitoring
Sway and tilt analysis
Industrial vibration controlSeismology

The JA-40GA accelerometer is therefore ideal for use
in structural health monitoring, active vibration control
systems and earthquake observation where the slightest
tremors are can be indicative of catastrophe.

To be exported in accordance with all relevant regulations.
