Product manual

Product Introduction

The GKM3 series triaxial accelerometer is a high-performance sensor product independently developed by RUICOM Technology, widely used in vibration monitoring, shock testing, and other fields. This product adopts an analog voltage output mode, supports address encoding settings, and can achieve multi-device cascading networking, facilitating the construction of distributed measurement systems.

Based on single-crystal silicon MEMS capacitive sensing technology, the GKM3 integrates high-precision ASIC signal conditioning circuitry, an embedded temperature compensation module, and a non-volatile memory unit, featuring low power consumption and high stability. The product undergoes rigorous calibration, ensuring reliable structure and excellent output signal consistency. Its innovative circuit design provides solid-state reset functionality and a comprehensive over voltage protection mechanism. With its robust mechanical structure, excellent zero-bias stability, and low power consumption, this series of products ensures accurate and reliable measurement data, meeting the stringent application requirements of industrial scenarios.
