Product Overview

The JB2 accelerometer family utilizes unique quartz flexible sensors for high-range (70g) acceleration measurement in aerospace environments. As the predominant sensor in China's commercial and military aircraft strap-down inertial navigation systems, it offers exceptional long-term repeatability and reliability.

Featuring a patented Q-flex® etched-quartz-flexure seismic system with amorphous quartz proof-mass structure, the JB2 provides excellent bias, scale factor, and axis alignment repeatability. The integral electronics produce an acceleration-proportional output current for both static and dynamic measurements, convertible to voltage via customer-supplied load resistors.

The optional internal temperature sensor enables dramatic performance improvements through temperature-compensating algorithms for bias, scale factor, and axis misalignment.

Key Features

Excellent turn-on repeatability performance
Environmentally rugged design
Analog output signal
