SUTRON XLink 100 Datalogger, Iridium Satellite


SUTRON’s XLink product family offers a cost-effective Wi-Fi enabled datalogger with data transmission via IRIDIUM® or Cellular. Ideal for use with multiple digital and analog sensors supporting basic or advanced hydrologic or meteorologic monitoring applications. The product comes in two models, the 100 and 500, tailored to fit different application and budget requirements. The XLink 100 and XLink 500 carry over all the great capabilities from its predecessor family (CDMALink, HSPALink, GPRSLink, IridiumLink).



Plug and Play Modem Card

Reduce modem setup time with automatic modem recognition. These modems are field exchangeable, enabling you to easily move from one telemetry type or Service carrier to another and to keep up with fast moving cellular/telecom technologies (e.g., 3G to 4G).

Two-way communication and remote configuration

Reduce time and cost of visiting field station to check, change or download configuration or turn on/off instruments. All datalogger features and configuration options available remotely via cell or Iridium, improving data access, and data retrieval, if transmissions are missed.

Simple and intuitive software

LinkComm software is usable with all Sutron XLink and SatLink 3 dataloggers, and is a common software that reduces training requirements. It allows simple setup over Wi-Fi using a smart phone, tablet or PC. You can also pair with Hydromet Cloud, a web-hosted software, to access and manage real-time data and alerts.

Secure communication

Send encrypted data over secure HTTPS, FTP(S) and password protected Socket (TCP/IP) transmission protocols.

Collect more data more often while in alarm

Reduce transmission costs by sending data more frequently only when data is needed at a faster interval using user definable alarm thresholds and adaptable intervals.
