Product Introduction

Quartz Flexure Accelerometers are precision instruments composed of quartz crystals and advanced inertia-based servo circuitry. When subjected to acceleration, the accelerometer's output is directly proportional to the input acceleration with high precision. Featuring a TTL output, our accelerometers enable users to read acceleration values directly. Compared to traditional I/F (current-to-frequency) circuits, this design eliminates intermediate conversion stages, resulting in higher accuracy.

At present, our quartz flexible accelerometers have formed a series of products. The models range from high-precision accelerometers used for satellite microgravity measurement to low-cost and environment-resistant accelerometers, totaling over ten types. They are widely applied in fields such as aerospace, aviation, navigation, ships, vehicles, petroleum, and geotechnical engineering, providing signals for systems such as navigation, guidance, control, leveling, and monitoring.
