The X2-SDL Submersible Data Logger is a rugged, self-powered remote data logging system for deploying environmental sensors in lakes, streams, rivers, wetlands, coastal waters, sewers, and culverts without fear of accidental flooding. The system is configured with three sensor ports for connection to industry-standard digital interfaces including RS-485, RS-232 and SDI-12. Additional sensor inputs are available through the use of adapters. Each sensor port offers a UW receptacle with double O-ring seal for a reliable waterproof connection. Unlike many data loggers, the X2-SDL is truly submersible. The housing and battery compartment are completely sealed and waterproof.

When it comes to field ruggedness, the NexSens X2-SDL is in a class of its own. The housing is constructed of impact-resistant PVC and includes two elastomer bumpers for long-term deployment in close-fitting pipes and buoy ports. Internal circuit boards and communication modules are shock mounted and all access ports incorporate redundant sealing. The X2-SDL withstands extreme wave action, drops, floods, periodic & long-term deployment underwater, and more. When fitted for wireless remote communication, the radio, cellular, and satellite antennas are also waterproof.

The X2-SDL can be powered autonomously by sixteen D-cell alkaline batteries. Optional solar power kits provide long-term continuous operation and solar charging. Common sensor connections include multiparameter sondes, water quality sensors, temperature strings, Doppler velocity meters, water level sensors, and weather stations. Optional integrated cellular or satellite telemetry modules offer real-time remote communications via the WQData LIVE web datacenter. There, data is presented on a fully-featured and easy-to-use dashboard. Other features include automated reports, alarms, push notifications and much more.

Questions & Answers
How long is the battery life for this logger?

The battery life is dependent on what sensors are connected, the measurement interval, and the transmit interval (if applicable). Contact us for a custom power budget tailored to your specific application.

Can data be retrieved via Wi-Fi?

Yes, data can be retrieved via an Internet Wi-Fi connection to the WQDataLIVE web datacenter. Alternatively, a UW6-USB-485P cable can be used to transfer data to a PC using CONNECT Software.

Can more than 3 sensors connect to this logger?

Yes, UW-2W and UW-4W splitters can accommodate more sensors: https://www.fondriest.com/nexsens-uw-2w-sensorbus-signal-splitter.htm

Can the X2-SDL data logger be deployed as-is, or does it need to be secured in place?

The X2-SDL data logger is available as a standalone package that can be fully submerged for extended periods of time. Mounts are available for underwater structures and instrument cages. For applications requiring wireless telemetry, the logger is typically secured above water on a fixed structure (stream bank, piling, etc.) or housed inside a CB-50 data buoy.

Are any sensors included with the X2-SDL?

The X2-SDL data logger integrates a temperature and humidity sensor for internal monitoring and diagnostics. It also measures and logs alkaline battery voltage so users can plan for maintenance trips to swap batteries. The logger has three native sensor ports available for external 12 VDC digital sensors including water quality, water level, weather, soil, etc. Two-way and four-way sensor splitters are available to increase the number of sensors that the logger can simultaneously support.

What auxiliary power options are available for the X2-SDL submersible data logger?

The X2-SDL data logger includes a 6-pin auxiliary power port compatible with the SBP500 submersible battery packs, SP-Series solar power packs, or any user-supplied 5-24 VDC power source.

Digital Mayfly Data Logger Sensor Stations Monitoring Watersheds

For most humans, mayflies seem like a nuisance, hovering over the waterways as we try to enjoy them. However, for anyone hoping to monitor the health of watersheds, mayflies are important aquatic species—and now, a digital version of the mayfly is helping some scientists keep an eye on the water. Research scientist Dr. Scott Ensign , who serves as Assistant Director of the Stroud Water Research Center , spoke to EM about how the digital mayfly technology developed. “ Shannon Hicks is the engineer who started developing the Mayfly six or seven years ago,” explains Dr. Ensign.

Engaging People, Engaging Lakes: How The Public Can Help Aquatic Systems

Jo Latimore’s interest in aquatic ecology dates back to her childhood, spending time at her parents’ North Michigan cabin, exploring the water nearby. Today she is a senior academic specialist, aquatic ecologist, and outreach specialist at Michigan State University in the Department of Fisheries and Wildlife , in her thirteenth year in the position. Latimore’s primary interests include lake appreciation and engagement.  “Most people appreciate our lakes. They like to look at, fish on, and boat on them. However, they don’t necessarily appreciate our lakes as an ecosystem,” Latimore said. “It’s the health of the lakes that lets us use them recreationally.

Aquatic Systems Connectivity: Finding Relationships Between Waters

An early aquatic science pioneer, Luna Leopold, said that “The health of our waters is the principal measure of how we live on the land.” Determining how the land impacts water quality, however, is complex. There must be an understanding of the flow of materials, organisms, and energy within our waters and how they are connected, or even whether they are connected. Enter the emerging field of aquatic systems connectivity.
