Quartz accelerometer is a high-precision inertial sensor that uses the piezoelectric properties of quartz crystals to measure acceleration.

A quartz accelerometer is a high-precision inertial sensor that uses the piezoelectric properties of quartz crystals to measure acceleration. It operates by detecting the charge generated when a force deforms the quartz crystal due to acceleration, which can then be converted to an electrical signal. They are known for excellent long-term stability, high reliability, and are widely used in applications like inertial navigation systems for aircraft and ships, as well as scientific research. China Professional Quartz Accelerometers supplier-Hitech Sensors Tech Co., Ltd

Working principle:

•  A quartz accelerometer is a type of piezoelectric sensor that utilizes the piezoelectric effect of quartz crystals.

•  When the sensor experiences acceleration, a force deforms the quartz crystal, which generates an electric charge.

•  This charge is measured and converted into an electrical signal proportional to the acceleration, allowing for the detection of both static and dynamic acceleration.

•  Some designs use a servo feedback system to provide an output current that is proportional to the acceleration. 

Key features and advantages:

•  High stability: Quartz has excellent long-term stability, making it suitable for applications that require precise and consistent measurements over time.

•  High reliability: The use of high-quality quartz crystals and robust designs leads to high reliability, especially in harsh environments.

•  High precision: They can achieve very high precision and sensitivity.

•  Flexibility: "Flexible" versions can adapt to high-temperature and high-pressure environments. 

Common applications:

•  Inertial navigation systems: Used in aircraft, ships, and other vehicles to provide accurate position and velocity data.

•  Aerospace and defense: Employed in high-performance inertial measurement units (IMUs).

•  Industrial and marine: Used in various industrial applications where high accuracy is critical.

•  Scientific research: Used for applications like earthquake and crustal movement studies, and cosmology.

•  Automotive: Sometimes used in automotive testing and control systems.
