Product Introduction

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

Product Features

【Diverse Parameters and High Precision】Measures displacement (deformation), tilt angle, acceleration, vibration frequency, amplitude, and temperature in 3D or 2D space. Real-time measurement of multiple related parameters (all or partial outputs selectable), enhancing the relevance of monitoring data;

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

【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 servers, or other acquisition instruments for easy integration;

【Torsion Self-Calibration Function】Torsion self-calibration (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; 2MPa (200m water depth) water pressure resistance, with an optional 4.5MPa (450m water depth) high-pressure version;
