    Introduction 
    ER-QA-03A High Performance Quartz Accelerometer with high reliability is mainly used in inertial measurement and test systems in the aerospace and aviation fields. It can carry out static test and dynamic test, which is a standard vibration sensor.

    Features
    The high performance quartz flexible accelerometer uses high-quality quartz crystals to achieve high precision acceleration measurement with extremely high reliability and stability. Its special flexible construction enables it to adapt to high acceleration applications under various environmental conditions, such as high temperature, high pressure and high vibration environments.

    Application
    In addition to being widely used in aerospace and military fields, high performance quartz flexible accelerometers are also widely used in automotive, medical and scientific research fields. In the field of scientific research, they can be used to study earthquakes, crustal movements, cosmology, and microgravity environments.
