GKM398 Product Exhibition Video:
The GKM398 triaxial Vibration sensor is an independently developed by RUICOM Technology, applicable to vibration testing, impact testing, and other fields. This product employs an analog current output design, supports address code settings, and allows multiple sensors to be used in series over long distances, facilitating multi-point measurement and data analysis.
The GKM398 utilizes single-crystal silicon capacitive sensing technology. Its core components include a micromachined silicon chip, a low-power ASIC signal conditioning circuit, a microprocessor for storing compensation data, and an integrated temperature sensor. The product undergoes precise calibration and features low power consumption, stable structure, and reliable output. Its electronic system employs a solid-state power supply reset design and provides overcurrent protection to ensure safe operation.
This series of products, with its robust structural design, excellent power consumption control, and good deviation stability, meets the requirements for high-reliability measurements.
