Product Introduction

The array displacement meter operates based on high-precision MEMS accelerometer arrays and is a sensor used for three-dimensional deformation monitoring. It is primarily employed to measure parameters such as displacement (deformation), inclination, and acceleration within three-dimensional space. It is widely used in various monitoring fields, including hydropower, railways, tunnels, slopes, tailings, and foundation pits, providing high-precision measurement data suitable for various complex working conditions and environments.

Product Features

【Diverse Parameters and High Precision】Real-time measurement of multiple related elements such as displacement (deformation), inclination, acceleration, vibration frequency, amplitude, and temperature in 3D or 2D space (all or partial outputs can be selected), enhancing the relevance of monitoring data;

【High Integration and Direct Data Output】Internally integrates data acquisition and computation modules, directly outputting data such as spatial coordinates, frequency, and amplitude without external calculation;

【Configurable Alarm Reporting】Internal threshold control enables real-time triggered alarms, improving data timeliness and effectiveness;

【High Compatibility with 485 Interface】Uses standard RS485 interface (default) or RS232 interface output, allowing direct connection to DTUs, serial port servers, or other acquisition instruments for easy integration;

【Torsion Self-Calibration Function】Torsion self-calibration function (suitable for settlement and convergence monitoring scenarios);

【Temperature Compensation to Reduce Drift】Built-in temperature measurement unit automatically performs temperature compensation, reducing sensor temperature drift;

【Lightning and Static Protection】Excellent lightning and static protection performance (±60kV/600W);

【Dustproof, Waterproof, and High Water Pressure Resistance】Sealing rating: IP68 dustproof and waterproof rating; 2MPa (200m water depth) water pressure resistance, with an optional 4.5MPa (450m water depth) high water pressure version;
