Product Introduction

The water level 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), inclination angle, and acceleration within three-dimensional space. It is widely applied in various monitoring fields including hydropower, railways, tunnels, slopes, tailings, foundation pits, and more, providing high-precision measurement data suitable for various complex working conditions and environments.

Product Features

【Diverse Parameters and High Precision】Displacement (deformation), inclination angle, acceleration, vibration frequency, amplitude, and temperature in three-dimensional or two-dimensional space. Real-time measurement of multiple related parameters (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, directly compatible with DTUs, serial port servers, or other acquisition instruments, making integration highly convenient;

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

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

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

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