Product manual

Product Introduction

The GKP3 is a triaxial vibration sensor independently developed for low-frequency vibration monitoring, featuring high precision and low noise. Each product undergoes calibration and compensation across the entire temperature range and approximately 336 hours of long-term stability testing before leaving the factory, ensuring stable performance under diverse operating conditions and continuous testing cycles. The sensor supports static vibration measurement in the 0Hz or 0.1–100Hz frequency bands and integrates two output protocols, including the industry-standard MODBUS protocol. The accompanying computer analysis software enables real-time display, recording, and subsequent processing of measurement data. Output interfaces offer RS485, RS232, and TTL options.

The sensor employs a non-contact installation design, facilitating system integration. Users simply need to fix it to the surface of the object being measured with screws to automatically obtain the object's horizontal angle, making operation simple. The product possesses excellent resistance to external electromagnetic interference and shock vibration, making it suitable for applications such as satellite communication systems, vehicle handling platforms, special command vehicles, and radar antenna vehicles.
