The Digitex D-Series Accelerometers are high-performance, MEMS accelerometers designed for permanent installations in Structural Health Monitoring (SHM), condition monitoring and earthquake engineering applications. All in all, the accelerometer offers uni-axial, bi-axial, and tri-axial models. Additionally, the D-Series provides a wide dynamic range, excellent bandwidth, and an ultra-low noise floor. Likewise, the rugged construction and precision performance make them ideal for long-term monitoring of civil, industrial, and geotechnical structures.
With its robust aluminum IP67 enclosure, integrated UPS battery, and advanced time synchronization modules, xPlorer ensures uninterrupted operation and precise alignment of data across large monitoring networks. Whether deployed on bridges, dams, tunnels, pipelines, or high-rise buildings, xPlorer is the cornerstone of our centralized SHM installations, enabling real-time decision-making and long-term performance insights.
Encased in rugged IP66/IP67 aluminum housings, D-Series accelerometers are built to withstand harsh outdoor conditions while delivering precise measurements. They feature analog differential outputs compatible with central acquisition systems such as xRover and xRover MAX. All models are powered from the central station (9–24 VDC) and can be easily mounted to most surfaces using specially designed levelling plates for accurate installation.
