Introduction
The Quartz Accelerometer is a high-performance, single-axis torque-feedback sensor that utilizes advanced quartz flexure structure and closed-loop servo technology. It precisely detects external acceleration signals and outputs a current signal proportional to the acceleration via a high-precision demodulation circuit. Engineered for extreme environments, this product excels in high-temperature resistance, vibration resistance, and shock resistance. It is widely applicable in aerospace high-precision navigation systems, oil drilling inclinometry, geological exploration, and other fields, providing reliable support for accurate measurements under complex operating conditions.
Technical Specification
The Quartz Accelerometer features an innovative quartz flexure pendulum design and torque-feedback closed-loop control technology, combined with an optimized temperature compensation algorithm. This ensures exceptional measurement accuracy and stability even under harsh conditions such as high temperatures (up to 180°C) and strong vibrations.
Its high-sensitivity servo circuit can demodulate and amplify weak signals in real-time, significantly enhancing dynamic response capabilities while maintaining excellent resistance to electromagnetic interference, meeting the requirements of industrial and military-grade applications. Additionally, its compact structural design allows for easy integration into space-constrained scenarios, providing users with a high-performance, reliable acceleration measurement solution.
