JA-40GA Accelerometer

Quartz Servo Accelerometers

JA-40GA

The JA-40GA is a high performance servo balanced quartz accelerometer which has been developed for measuring 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.
