Dataloggers

XLink

The Sutron XLink datalogger is a cost-effective, Wi-Fi enabled environmental data logger designed for reliable data collection and transmission via cellular or Iridium satellite telemetry. Built to support both basic and advanced monitoring applications, the Sutron XLink is ideal for sites requiring flexible sensor inputs, low power operation, and secure remote access.

Available in XLink 100 and XLink 500 models, the Sutron XLink carries forward the proven capabilities of earlier Sutron platforms including CDMALink, HSPALink, GPRSLink, and IridiumLink, all while introducing modern communications, expanded processing power, and simplified configuration.

Multi-Sensor Datalogger with Wi-Fi

The Sutron XLink datalogger is a true multi-sensor input data logger, supporting a wide range of digital and analog sensors for hydrological, environmental, and infrastructure monitoring.

Built-in Wi-Fi capability allows complete station setup, configuration, and data access using a smartphone, tablet, or PC, eliminating the need for physical connections during commissioning and maintenance.

Applications

The Sutron XLink is well suited for a wide range of monitoring applications, including:

• Surface water and stream gauging
• Water quality monitoring
• Basic and advanced meteorological stations
• Flood monitoring and early warning systems
• Environmental and infrastructure monitoring

Plus & Play Telemetery

The Sutron XLink uses field-exchangeable, plug and play modem cards to simplify telemetry deployment and future upgrades.

• Automatic modem recognition reduces setup time
• Easily change telemetry type or service carrier in the field
• Supports cellular and Iridium communications
• Keeps pace with evolving cellular technologies (e.g. 3G to 4G/LTE)

This modular approach protects long-term investment and simplifies fleet management.

Custom Programming with Python (XLink 500)

The Sutron XLink 500 supports advanced applications through Python scripting, enabling functionality beyond standard configuration.

• Create custom measurements and calculations
• Define custom transmission formats and logic
• Automate site-specific workflows
• Leverage a modern, easy-to-learn programming language

Python support allows the XLink 500 to adapt to complex or non-standard monitoring requirements.

Two Way Communication

The Sutron XLink datalogger supports full two-way communication, allowing complete remote access to configuration, diagnostics, and data.

• Change settings remotely via cellular or satellite
• Reduce site visits and operational costs
• Request missing data if transmissions are interrupted
• Remotely enable or disable connected instruments

This capability significantly improves responsiveness and system uptime.

LinkComm Software

All Sutron XLink dataloggers are configured using LinkComm software, providing a consistent user experience across Sutron platforms.

• Common software reduces training requirements
• Simple setup over Wi-Fi using phone, tablet, or PC
• Supports local and remote configuration

• Compatible with HydroMet Cloud for real-time data access, alerts, and management.

USB Support

The Sutron XLink datalogger supports USB flash drives for fast field servicing and updates.

• Automatically download logged data, diagnostics, and events
• Quickly modify configuration files
• Upgrade firmware without a PC
• Load Python scripts (XLink 500)

This simplifies maintenance in remote or access-limited locations.

Alarm Based Data Transmission

The Sutron XLink datalogger optimises data transmission costs by adapting logging and transmission behaviour during events.

• User-defined alarm thresholds
• Increased logging and transmission frequency during alarms
• Reduced data usage during normal conditions
• Faster access to critical data when it matters most

Secure Data Transmission

The Sutron XLink datalogger supports secure data transmission using modern encryption standards.

• Encrypted HTTPS communication
• Supports HTTP(S), FTP(S), and TCP/IP socket protocols
• Secure data delivery to servers and cloud platforms

This ensures data integrity and compliance with modern IT and cybersecurity requirements.

Low Power Design

The Sutron XLink datalogger features a small footprint that reduces enclosure size, power consumption, and installation costs.

• Ideal for solar-powered and battery-powered sites
• Easy to conceal in public or sensitive locations
• Reduces overall system footprint

Multiple Interfaces & Protocols

The Sutron XLink datalogger is compatible with a wide range of sensors, protocols, and output formats.

• SDI-12 sensor support
• RS-232 and RS-485 interfaces
• SDI-12 over RS-485
• Modbus (Master or Slave, RTU or ASCII)
• Supports ASCII, CSV, SHEF, Pseudobinary, and OTT MIS formats
• Easy integration with external modems and displays
