Miniature Acceleration Transducers ACC-II-352C

To meet the requirements of high precision, high repeatability and high frequency response for vibration acceleration measurement in model tests of various soils and geotechnical structures under multi‑field coupling conditions, as well as to adapt to special testing environments such as dynamic centrifuge model tests and shaking table tests, strict standards are often required for the miniaturization and frequency response characteristics of vibration acceleration sensors. In addition, it is necessary to minimize the range of flow field disturbance to ensure the acquisition of accurate and reliable variation laws of vibration acceleration.

The ACC‑II‑352C miniature acceleration sensor is developed and designed to meet the above working conditions. Adopting advanced domestic ICP piezoelectric ceramic technology and integrated with state‑of‑the‑art miniaturized fabrication and packaging processes, this sensor features small size, light weight, wide dynamic range, broad frequency response, robust structure and strong anti‑interference ability.
