    ER-QA-01C Low Cost Quartz Accelerometer 

    Low Cost Quartz Accelerometer can be widely used in inertial navigation system which has wide application in aerospace vehicles, inertial navigation system and control system of ships.

    Composition and characteristics:

    Quartz flexible pendulum accelerometer is composed of a meter head and a matching circuit. The head part of the watch is composed of inertia mass pendulum (with torque coil), torque tester, position detector, quartz pendulum plate, etc. Quartz flexible pendulum accelerometer is characterized by small size, high precision, fast start, impact resistance, and can meet the requirements of a variety of carriers and inertial systems.
