Product Description

Unique Quartz Flexible Sensors High-Range(70g) Accelerometer With Temperature Sensor


JB2 accelerometer family utilizes unique quartz flexible sensors. The high-range(70g) 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 JB2 make it the best value inertial-grade accelerometer available on the market today.

JB2 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.

The JB2 also includes a current-output, internal temperature sensor. By applying temperature-compensating algorithms, bias, scale factor, and axis misalignment performance are dramatically improved.
