Centralized Structural Health Monitoring System

High-density, rack-mounted acquisition with lab-grade accuracy for any SHM project. Simply put, the xCas is a centralized SHM solution based on a single hub that powers and clocks every channel, simplifying cabling while delivering ultra-low noise data, precise time synchronization, and effortless expansion.

Overview

xCAS® is Digitex Systems’ Central Data Acquisition System for Structural Health Monitoring (SHM). Firstly, we designed it around a powerful central unit (xRover) that digitizes, synchronizes, stores, and analyzes multi‑channel analog sensor data in real time.

Additionally, xCAS is ideal for proactive maintenance projects that require a centralized topology—labs, control rooms, and sites where cabling to a central point is practical.

Additionally, the centralized SHM solution is ideal for customers who want high channel density, unified timing, and simple, all‑in‑one operation.

Description

At the heart of xCAS is the xRover, a central data acquisition and digitizer unit. It provides high‑performance A/D conversion, precise GPS/DigiSync® timing, secure local storage (Ring Buffer + events), in addition to the integrated Voyager® software for configuration, visualization, triggering, reporting, and streaming.

This centralized SHM solution accepts a broad range of analog inputs—high-precision vibration measurement (accelerometers), velocity measurement (geophones), strain gauges/bridge sensors, voltage/current transducers, temperature (RTD), and weather stations. Moreover, these options make the xCas a versatile platform for modal, seismic, and long‑term structural monitoring.

xCAS is tailored according to the needs of each project. Channel counts, input ranges, and signal conditioning are configured to match the customer’s sensors and measurement goals.

Additionally, for operators who prefer a consolelike experience, xRover MAX integrates a 10” touchscreen that exposes the full Voyager UI directly on the device while still supporting remote access from a browser or client PC. Besides, the centralized SHM solution enables optional cloud connectivity for offsite backup, fleet management, and live dashboards.

Structural Health Monitoring Applications

xCAS is suited for projects that benefit from a central measurement hub:

  • Civil structures: bridges, buildings, dams, tunnels, stadiums
  • Research & test facilities: structural labs, proof‑of‑concept rigs, educational labs
  • Industrial assets: plants, pipelines, towers, cranes, wind energy
  • Long‑term monitoring where central wiring and unified control are preferred

Key Features of the Centralized Structural Health Monitoring System

  • High‑Channel Acquisition

    Scalable channel counts in addition to high‑performance 24‑/32‑bit A/D converters, anti‑aliasing filters, and per‑channel configuration.

  • Sensor Compatibility

    Supports D‑Series analog accelerometers, including a wide range of analog sensors (±10V/±5V, 0‑10V/0‑5V, 4‑20mA/0‑20mA, full‑bridge/6‑wire strain, PT100/PT1000 RTD).

  • Integrated Voyager®

    Real‑time configuration, particularly triggering (Leveling, STA/LTA, Above Max, Below Min, Relative, OMA‑assisted), storage, reporting (Time, FFT, PA, PV, PD, P‑P), and much more besides the data streaming.

  • Accurate Time Sync

    GPS/DigiSync® provides sub‑millisecond alignment across all channels including external systems.

  • Reliable Storage & Redundancy

    Local SSD Ring Buffer (user‑configurable duration), event files, and optional secure FTP/cloud backup.

  • Connectivity

    Multi‑port Ethernet, Wi‑Fi, optional DigiMESH® and GSM/4G for the purpose of remote access; embedded SeedLink server for MiniSEED streaming.

  • Alarming & Automations

    Configurable relay outputs and notifications (SMS/email) mapped to triggers including pre‑/post‑event buffers, optional distributed relay panels.

  • xRover MAX Option

    Integrated 10” touchscreen with full Voyager UI for local control and visualization.

  • Rugged & Serviceable

    Industrial‑grade enclosure including wide temperature operation, OTA firmware updates, and secure web UI.

  • Wide Sensor Compatibility

    Besides accelerometers the centralized SHM solution supports displacement sensors, strain gauges, temperature sensors, pressure, wind, inclination, piezometers, and many more Structural Health Monitoring sensors.
